Suing the city will just get passed on to the taxpayers. The cop and his superiors need to be personally sued.
Bet me...
Here is what ya do.
Give this guy a 10 million dollar cash award, and then to pay for it, reduce the salaries of every single over paid government employee in the city, and as a bonus, fire the cop involved, and cut the police chiefs and mayors salary in half.
Do it!
Agreed, the cop and everyone above him should lose everything they have, but if the taxpayers feel the heat they will start making sure this crap doesn’t happen again.
