Dec 21, 2011 4:45 AM EST                                                                      
Nestled  amid plains so flat the locals joke you can watch your dog run away for  miles, Fargo treasures its placid lifestyle, seldom pierced by the  mayhem and violence common in other urban communities. 
North Dakota's  largest city has averaged fewer than two homicides a year since 2005,  and there's not been a single international terrorism prosecution in the  last decade.
 
But that hasn't stopped  authorities in Fargo and its surrounding county from going on an $8  million buying spree to arm police officers with the sort of gear once  reserved only for soldiers fighting foreign wars.
Every city squad car is equipped  today with a military-style assault rifle, and officers can don Kevlar  helmets able to withstand incoming fire from battlefield-grade  ammunition. And for that epic confrontation—if it ever occurs—officers  can now summon a new $256,643 armored truck, complete with a rotating  turret. For now, though, the menacing truck is used mostly for training  and appearances at the annual city picnic, where it's been parked near  the children's bounce house.
"Most people are so fascinated by  it, because nothing happens here," says Carol Archbold, a Fargo resident  and criminal justice professor at North Dakota State University.  "There's no terrorism here."
Like Fargo, thousands of other  local police departments nationwide have been amassing stockpiles of  military-style equipment in the name of homeland security, aided by more  than $34 billion in federal grants since the Sept. 11, 2001, terrorist  attacks, a Daily Beast investigation conducted by the 
Center for Investigative Reporting has found.

The buying spree has transformed  local police departments into small, army-like forces, and put  intimidating equipment into the hands of civilian officers. And that is  raising questions about whether the strategy has gone too far, creating a  culture and capability that jeopardizes public safety and civil rights  while creating an expensive false sense of security.
"The argument for up-armoring is  always based on the least likely of terrorist scenarios," says Mark  Randol, a former terrorism expert at the Congressional Research Service,  the nonpartisan research arm of Congress. "Anyone can get a gun and  shoot up stuff. No amount of SWAT equipment can stop that."
Local police bristle at the  suggestion that they've become "militarized," arguing the upgrade in  firepower and other equipment is necessary to combat criminals with more  lethal capabilities. They point to the 1997 Los Angeles-area bank  robbers who pinned police for hours with assault weapons, the  gun-wielding student who perpetrated the Virginia Tech massacre in 2007,  and the terrorists who waged a 
bloody rampage in Mumbai, India, that left 164 people dead and 300 wounded in 2008.
 
The new weaponry and battle gear,  they insist, helps save lives in the face of such threats. "I don't see  us as militarizing police; I see us as keeping abreast with society,"  former Los Angeles Police chief William Bratton says. "And we are a  gun-crazy society."
"I don't see us as militarizing police; I see us as keeping abreast with society."
Adds Fargo Police Lt. Ross Renner,  who commands the regional SWAT team: "It's foolish to not be cognizant  of the threats out there, whether it's New York, Los Angeles, or Fargo.  Our residents have the right to be protected. We don't have everyday  threats here when it comes to terrorism, but we are asked to be  prepared."
The skepticism about the Homeland  spending spree is less severe for Washington, D.C., Los Angeles and New  York, which are presumed to be likelier targets. But questions persist  about whether money was handed out elsewhere with any regard for risk  assessment or need. And the gap in accounting for the decade-long  spending spree is undeniable. The U.S. Homeland Security Department says  it doesn't closely track what's been bought with its tax dollars or how  the equipment is used. State and local governments don't maintain  uniform records either.
To assess the changes in law  enforcement for The Daily Beast, the Center for Investigative Reporting  conducted interviews and reviewed grant spending records obtained  through open records requests in 41 states. The probe found stockpiles  of weaponry and military-style protective equipment worthy of a defense  contractor's sales catalog.
In  Montgomery County, Texas, the sheriff's department owns a $300,000  pilotless surveillance drone, like those used to hunt down al Qaeda  terrorists in the remote tribal regions of Pakistan and Afghanistan. In  Augusta, Maine, with fewer than 20,000 people and where an officer  hasn't died from gunfire in the line of duty in more than 125 years,  police bought eight $1,500 tactical vests. Police in Des Moines, Iowa,  bought two $180,000 bomb-disarming robots, while an Arizona sheriff is  now the proud owner of a surplus Army tank.
 
The flood  of money opened to local police after 9/11, but slowed slightly in  recent years. Still, the Department of Homeland Security awarded more  than $2 billion in grants to local police in 2011, and President Obama's  2009 American Recovery and Reinvestment Act contributed an additional  half-billion dollars.
Law  enforcement officials say the armored vehicles, assault weapons, and  combat uniforms used by their officers provide a public safety benefit  beyond their advertised capabilities, creating a sort of "shock and awe"  experience they hope will encourage suspects to surrender more quickly.
"The only  time I hear the complaint of 'God, you guys look scary' is if the  incident turns out to be nothing," says West Hartford, Conn., Police Lt.  Jeremy Clark, who organizes an annual SWAT competition.
A grainy  YouTube video from one of Clark's recent competitions shows just how far  the police transformation has come, displaying officers in battle  fatigues, helmets, and multi-pocketed vests storming a hostile scene.  One with a pistol strapped to his hip swings a battering ram into a  door. A colleague lobs a flash-bang grenade into a field. Another  officer, holding a pistol and wearing a rifle strapped to his back,  peeks cautiously inside a bus.
The images unfold to the pulsing, ominous soundtrack of a popular videogame, 
Call of Duty: Modern Warfare 2. Though resembling soldiers in a far-flung war zone, the stars of this video are Massachusetts State Police troopers.
 
The number  of SWAT teams participating in Clark's event doubled to 40 between 2004  and 2009 as Homeland's police funding swelled. The competition provides  real-life scenarios for training, and Clark believes it is essential,  because he fears many SWAT teams are falling below the 16 hours of  minimum monthly training recommended by the National Tactical Officers  Association.
"Luck is not for cops. Luck is for drunks and fools," Clark said, explaining his devotion to training.
One  beneficiary of Homeland's largesse are military contractors, who have  found a new market for their wares and sponsor training events like the  one Clark oversees in Connecticut or a similar Urban Shield event held  in California.
Special ops  supplier Blackhawk Industries, founded by a former Navy SEAL, was among  several Urban Shield sponsors this year. Other sponsors for such  training peddle wares like ThunderSledge breaching tools for smashing  open locked or chained doors, Lenco Armored Vehicles bulletproof box  trucks, and KDH Defense Systems's body armor.
"As  criminal organizations are increasingly armed with military-style  weapons, law enforcement operations require the same level of  field-tested and combat-proven protection used by soldiers and Marines  in Iraq, Afghanistan, and other high-risk locations," boasts an Oshkosh  Corp. brochure at a recent police seminar, where the company pitched its  "tactical protector vehicle."
The trend  shows no sign of abating. The homeland security market for state and  local agencies is projected to reach $19.2 billion by 2014, up from an  estimated $15.8 billion in fiscal 2009, according to the Homeland  Security Research Corp.
The rise of  equipment purchases has paralleled an apparent increase in local SWAT  teams, but reliable numbers are hard to come by. The National Tactical  Officers Association, which provides training and develops SWAT  standards, says it currently has about 1,650 team memberships, up from  1,026 in 2000.
Many of  America's newly armed officers are ex-military veterans from the front  lines of Iraq and Afghanistan. Charles Ramsey, who was police chief in  Washington, D.C., on 9/11, upgraded the weaponry when he moved to  Philadelphia in 2008. Today, some 1,500 Philly beat cops are trained to  use AR-15 assault rifles.
"We have a  lot of people here, like most departments, who are ex-military," Ramsey  says. "Some people are very much into guns and so forth. So it wasn't  hard to find volunteers."
Some  real-life episodes, however, are sparking a debate about whether all  that gear also creates a more militarized mind-set for local police that  exceeds their mission or risks public safety.
In one  case, dozens of officers in combat-style gear raided a youth rave in  Utah as a police helicopter buzzed overhead. An online video shows the  battle-ready team wearing masks and brandishing rifles as they holler  for the music to be shut off and pin partygoers to the ground.
And Arizona  tactical officers this year sprayed the home of ex-Marine Jose Guerena  with gunfire as he stood in a hallway with a rifle that he did not fire.  He was hit 22 times and died. Police had targeted the man's older  brother in a narcotics-trafficking probe, but nothing illegal was found  in the younger Guerena's home, and no related arrests had been made  months after the raid.
In  Maryland, officials finally began collecting data on tactical raids  after police in 2008 burst into the home of a local mayor and killed his  two dogs in a case in which the mayor's home was used as a dropoff for  drug deal. The mayor's family had nothing to do with criminal activity.
Such  episodes and the sheer magnitude of the expenditures over the last  decade raise legitimate questions about whether taxpayers have gotten  their money's worth and whether police might have assumed more might and  capability than is necessary for civilian forces.
"With local  law enforcement, their mission is to solve crimes after they've  happened, and to ensure that people's constitutional rights are  protected in the process," says Jesselyn McCurdy, senior legislative  counsel for the American Civil Liberties Union. "The military obviously  has a mission where they are fighting an enemy. When you use military  tactics in the context of law enforcement, the missions don't match, and  that's when you see trouble with the overmilitarization of police."
The upgrading of local police nonetheless continues. 
Arizona Sheriff Joe Arpaio  now claims to operate his own air armada of private pilots—dubbed  Operation Desert Sky—to monitor illegal border crossings, and he  recently added a full-size surplus Army tank. New York Police  Commissioner Ray Kelly boasted this fall he had a secret capability to  shoot down an airliner if one threatened the city again. And the city of  Ogden, Utah, is launching a 54-foot, remote-controlled "crime-fighting  blimp" with a powerful surveillance camera.
 
Back in  Fargo, nearby corn and soybean farmer Tim Kozojed supports the local  police but questions whether the Homeland grants have been spent wisely.  "I'm very reluctant to get anxious about a terrorist attack in North  Dakota," Kozojed, 31, said. "Why would they bother?"
