Police defend a guy who slashed the ear of a young girl with a box cutter.

A guy caught him and turned him over to police.

The guy got away. Oops.

The same guy that caught him the first time got him again. They let the assailant get away again. Oops.

A mob from Harlem caught him. So the police surrounded him to protect him.
