Mark Blake Jr. is acting as his own lawyer—although he does have a public defender at his side in case he wants legal advice—as he stands accused of attempted murder of a police officer during a 2013 traffic stop.

Blake faces up to 30 years in prison for attempted murder in the March 13, 2013, shooting of Charleston Police Officer Cory Goldstein, according to WCSC-TV.

Goldstein—who no longer works for the Charleston Police Department—took the stand to recount the night of the shooting. He told the jury that during the foot chase, Blake kept looking over his shoulder to see how close Goldstein was to him.

He said that after Blake had stopped, he ordered Blake not to move, and Blake responded, "You don't move [expletive]," and opened fire.

Blake then had the opportunity to cross-examine the officer he is accused of trying to kill.
