If the NYPD police had APCs or Bradly fighting vehicles could they have prevented the 9/11 attacks on the WTC in Manhattan -- NO. If they had the immediate use of FIM-92 Stinger missiles would the police had shot down the second civilian aircraft before it crashed into the other WTC building minutes later -- probably not, where would it have crashed? The USAF sat unwilling to shoot down the planes save for the cost of collateral damage, unknown perhaps that the planes' occupants were doomed to a fiery death at the hands of terrorists. (Discounting the conspiracy theorists versions of that day's events.)

If the Boston Police had APCs or Bradly fighting vehicles could they have prevented the Boston Marathon Bombing -- NO.

So why the hell do the police need APCs or Bradly fighting vehicles, 100 round assault rifles or silencers for their guns? Flack jackets, military police equipment, encrypted field communications gear, normal weapons and military grade ammo -- OK. Even surplus aircraft and helicopters. But APCs or Bradly fighting vehicles, maybe TOW missiles or other battlefields weapons?

Is the destiny of your city in America to become a battlefield for paramilitary police SWAT or counter-terrorism forces? You don't think drug traffickers and organized crime will take notice and obtain better hardware? This will cause escalation of super violent crime and less thought given to shooting of police that are not heavily armed, just performing civilian law enforcement duties.
