The number of individuals pretending to be police to gain initial complaince during home invasions seems to be increasing. There is many reports of such situations across the nation. Here is a complilation of just a few for examples: 2 men dressed with shirts saying 'police' and yelling police in a home invasion: http://www.youtube.com/watch?v=SBA3psWTB2w&feature=related 911 call of a woman robbed by 5 men dressed as police: http://www.youtube.com/watch?v=qVhdK8nL9l0 Robbers yelling "police, police" smash down front door and hold women hostage looking for drugs, then realize they got the wrong address and leave (taking laptop and video game system.) http://www.youtube.com/watch?v=oY0zbH8uUjA 4 men dressed as law enforcement involved in spree of 9 robberies: http://www.msnbc.msn.com/id/25678456/ http://www.azcentral.com/news/articles/2008/06/27/20080627abrk-homeinvasion0627.html Men dressed in police raid gear, ex mexican military raid a home, and references are made to previous incident by same individuals in which over 100 shots were fired: http://news.ktar.com/?nid=6&sid=879606 It goes on and on. Many similar incidents in the last year of individuals claiming to be police, dressed as police, using such a tactic to gain an advantage during criminal acts. Of course since police actualy do these type of invasions it is a good ploy, they even get the address wrong on occasion or are wrongly called to an address by a criminal prankster. When people fight back they can sometimes be charged, like in the case of Cory Maye, when it actualy was police. He now sits in prison with a life sentence, previously a death sentence. Clearly pretending to be police is a great tactic. In fact I do not know why it is not the standard tactic for home invaders. They can put on effective gear, and gain additional compliance from victims. Clearly a big part of the problem is police actualy conduct such raids. Often in an attempt to secure some substance, when an actual arrest of a subject could have easily been made another way. This is not a "cop bashing" but rather a question about allowing such policies in a nation where households are expected to be armed. It undermines the ability of law abiding people to defend themselves when someone pretending to be police chooses to make them a victim. Many people use the term "no knock" wrong. No knock raids are rare. Instead very quick knocks often in combination with "police search warrant" followed immediately by smashing down the door are far more common. All is often done in a matter of seconds, long before someone could actualy make it to the door to answer it (or more importantly hide some sort of evidence.) "No knocks" are when no announcement is made. So don't confuse the two when discussing the situation. This is not an invitation to bash cops, they are people, and all professions have people who do bad things, have honest and corrupt individuals etc. Instead this is to discuss the situation of criminals using the ploy of being officers.
