The mayor of Memphis said billboards put up by the Memphis Police Association are hurting the city’s image and calls the message, “selfish.”

The police union billboards feature the warning, “DANGER: Enter at your own risk; This city does not support public safety,” reported.

Mike Williams, the president of the MPA, said the billboards are meant to target city leaders and are about protecting union’s jobs and benefits.

“I think it’s self-centered, I think it’s selfish,” Memphis Mayor A C Wharton said. “I think it has no place in our city.”
