In January 2011, wheelchair-bound Randal Dunklin, 55, was denied services at a mental health clinic in San Francisco. Outside the clinic, he grew upset and began vandalizing cars. He pulled out a knife, prompting police to arrive at the scene. When he wouldn't drop the weapon, plainclothes officers pepper-sprayed him, and Dunklin stabbed one of them in the arm. The police shot him.
