Guy charged with firing at cops no stranger to police

John Mentor, 22, of Hyde Park, who allegedly took a shot at cops in Hyde Park last night, is scheduled for arraignment in West Roxbury District Court this morning on a charge of assault with intent to murder, according to the Suffolk County DA's office.

In 2005, when he was 18, Mentor and a pal were arrested on charges they robbed and shook down younger teens on buses out of Forest Hills. He was also charged with cocaine possession.

Innocent, etc.
