Just blame it on a black guy.

A white security officer told police he was shot by a black man.
Within minutes, 55 officers swarmed the campus, along with four police dogs and a State Patrol aircraft to search for the suspect.
Ahlers, the 'victim', was taken to the hospital and released. He is expected to make a full recovery.
At a news conference, police spokesman Mike Ernster said the campus had been on lockdown with “1,800 student held captive in their dorm rooms.”
Neighborhood residents, shaken by reports of a gunman at large, asked police officers to check their houses.
Turns out, he’d shot himself.
