The unusual lawsuit was filed Friday amid city leaders' efforts to win back the public's trust
after several cases of alleged police misconduct.
Robert Rialmo's lawsuit provides the officer's first public account of how he says the Dec. 26 shooting happened. It says Rialmo opened fire after Quintonio LeGrier swung a bat at his head at close range.
LeGrier's father, Antonio LeGrier, filed a wrongful death lawsuit saying his son wasn't a threat. His attorney, Basileios Foutris, did not return messages seeking comment on the countersuit.
