The attorney representing Los Angeles police officer Houston Tipping's mother claims that the 32-year-old was targeted by other officers for being a potential whistleblower.Even though a coroner's report ruled Tipping's death an accident, attorney Brad Gage says he was targeted because he was a whistleblower in an assault case involving other officers."LAPD claims in Public Records Act requests there was no incident report at all," said Gage."The problem with that is other medical reports show the LUCAS device was never used," Gage said.Gage said he has not been able to speak to any of the paramedics about the treatment that was given to Tipping."
