Rich, the officer has a remedy here - it's called W. Comp. It's also the exclusive remedy against an employer in TX, hence why the bloodsucking lawyer is targeting the woman instead of the city (where the really deep pockets are).
Also, I'd like to be clear that I'm not questioning what the LEO did AT the scene in the heat of the moment... Just what he's done afterwards, with plenty of time to think about it.
