Maybe this is old news to a lot of you, but while on youtube recently under "suggestions" was a video about the BATF's program of releasing hundreds of guns into Mexico, some of which may have been used to kill a US border patrol agent. And of course the obligatory cover-up afterwards.
Here's the particular video that I saw:
YouTube - ‪GOOD COPS, BAD COPS and a LYING GOVERNMENT.‬‏
There's also a wiki entry on it if you prefer something with a little less commentary:
Operation Fast and Furious - Wikipedia, the free encyclopedia
The sad thing is I'm not really sure if I was surprised or not. Of course we had the Iran-Contra scandal back in the 80's and right now the US military is officially protecting opium fields, so should I be shocked that one of the main agencies in charge of enforcing firearms regulations is itself breaking the law? I guess not.
