Per this report, a former cop who worked a security job with Mateen says he was a creep and believes his conduct got a pass for the usual reason:
Gilroy, a former Fort Pierce police officer, said Mateen frequently made homophobic and racial comments. Gilroy said he complained to his employer several times but it did nothing because he was Muslim. Gilroy quit after he said Mateen began stalking him via multiple text messages — 20 or 30 a day. He also sent Gilroy 13 to 15 phone messages a day, he said.
“I quit because everything he said was toxic,” Gilroy said Sunday, “and the company wouldn’t do anything. This guy was unhinged and unstable. He talked of killing people.”
Gilroy said this shooting didn’t come as a surprise to him.
