“Powerful drug cartels are increasingly using gruesome videos of executions and interrogations to intimidate their rivals, police and an already terrified public in Mexico’s vicious drug war.

In one video, a man with a black eye is tethered to a chair in his underwear and appears to be strangled to death with a tourniquet by his captors. There is a “Z” scrawled across his chest, for Zetas, a spinoff of the Gulf Cartel.

In another video, a man is slowly beheaded with a knife.”

Seems somehow familiar…where have we seen this tactic before…?
