I saw an interview tonight on ABC News with a gal who runs a bar there. She said that the cop, and the dead Negro, both worked security at her bar at the same time.
She said the cop was pretty good but sometimes, got a little out of hand, like when "he pepper sprayed the entire bar room for no good reason."

As someone said, any good street cop is going to have complaints lodged against him in this day and age.

ps. The gal's bar room was burned down last night.

ps2. How do you hire a guy for security who has a conviction for a home break in and armed robbery. This guy should have still been in prison in Texas.
