He was probably holding his pants up. Itchy trigger finger.
Itchy trigger finger my ass! If the story as written is fact. I would call it a good shoot. Lara was told several times in English AND Spanish to show both hands WHILE HE WAS WALKING AWAY from the cop. He did not. Then he turned toward the officer with his hand still under his shirt. What would you have her do? Wait until he fired a weapon before shooting? Let him go since he was only fighting with other drunks? I seriously doubt the city of Houston hires police officers to any of these. Cops are not supposed to lose any fight. Regardless of your opinion of cops, they like you, have the right to go home after work.
