“If the charges against the police officers arrested this morning prove true, it would be a disgraceful and deplorable betrayal of the public trust,” Mayor Michael Bloomberg said in a statement quoted by Newsday. “The fact that these were inoperable guns does not change the fact, if the charges prove true, that the officers violated their sacred oath.” Wait? What? I got that “bad apple” and “don’t piss on the police union” bit. Let’s talk about the firearms. The New York Times reports that the FBI did the rendering thing on 20 firearms including three M-16 rifles, a shotgun and 16 handguns. But how? TTAG commentator ready,fire,air [below] reckons the feds copied the firing pin shortening schtick from the movie Shooter. Stranger things have happened.
