Men stabbed for throwing gang signs that were actually just ASL

On Saturday night at a bar near Miami, Florida, 45-year-old Barbara Lee became angry at what she thought were several men throwing gang signs at her. She returned with a male friend who stabbed two of the men. Turns out, the men were deaf and using sign language. Lee and her friend were charged with assault with a deadly weapon. The story was reported in an NBC Miami article that, incidentally, refers to one of the men as "mute" which I always understood to be an obsolete term and offensive to many. Seems like these men, while perhaps not using their voices, could communicate just fine. Lee and her other brilliant friends were just too stupid to realize they were using a different, and rather common, language. From NBC Miami:

Instead, Lee left and then shortly returned to the bar with a juvenile and 19-year-old Marco Ibanez, who is accused of pulling out a knife and stabbing the men.

In the ensuing melee, the deaf men suffered stab wounds to the torso and back while the intervening bouncer whas struck on the head with a bottle.
