Prison Riot: CCTV shows HEAVILY armed inmates during Mexico uprising - Gunrunner???

This is serious hardware.

Looks to be handguns, MP5, and AK pistol (AK with pistol grip instead of butt-stop and sometimes shorter barrels).

I think it's more likely that these guys are not actual prisoners, but came from the outside with these weapons, judging by their clothing... and the whole being armed thing.

They were probably there to silence someone who was picked up, or attacking someone who had hit their gang previously who was now being held in detention at the facility.

Either way, who wants to make bets that it comes out that at least one of the weapons was from Operation Gunrunner???

The guards in one prison were letting gangstas out to do hits on rivals at night, and the hitmen were in some cases borrowing their guns from the guards....the perfect alibi...."I was incarcerated!"
This is pretty light duty weaponry really....scarey enough however.....

not shocking...america isnt anything less shocking regarding weapons in the hands of bad people...
