George Zimmerman -- Plays Death Threat Card to Dodge Window Tint Ticket

George Zimmerman needs to keep a low profile -- behind super dark tinted windows -- because he's getting death threats ... at least that's what Zimmerman told Florida cops.

Zimmerman was pulled over last month by a Florida Highway Patrol officer who told him the tint on his truck was too dark, and his license plate was not displayed properly.

Zimmerman told the cop he needed the extra cover because he's been getting death threats. He was not more specific about the nature of the threats.

Instead of getting slapped with a ticket for the violation, Zimmerman caught a break ... again.
