I first saw the weapons on the news reports when it was happening and was fairly positive of the identification. I also talked to a friend (currently a Firefighter in Arizona, but formally LAPD) who had spoken with LAPD friends about the robbery and firefight. He told me that A&E was filming a documentary piece that would show both rifles.
When I watched the A&E piece, they only show the HK 91, but they fired the Chinese AKM! Some of the officers that were shot were interviewed as well.
Guns cause crime like spoons cause Rosie O'Donnell to be fat!
May your lead always hit center mass and your brass always land in your range bag.
