Security camera footage shows the brutal assassination of Mexican police by heavily armed narcoterrorists.
The video begins by showing an occupied police pickup truck sitting at a gas station. The Mexican cops are completely oblivious to what is about to take place.
A Ram truck rapidly pulls up alongside the officers' vehicle and close range fully automatic gun fire rips into the police.
The sicarios dump dozens of rounds into the officers and another group of dismounted thugs enters the frame from the right. The second group of cartel members shoots and kills a man taking fire behind one of the fuel pumps.
It is unclear if the executed man is a police officer or just an innocent bystander, but he was wholly unaware of the second group of assassins approaching from behind.
