Cop Killer?

Re “John Did It” (11/12): Is John a cop? When Derrick Jefferson, apparently a petty drug dealer, was shot, he said, “John did it.” He lived several days, but the police never questioned him. He died, and the police did not investigate for a month. Then a detective accused an innocent man and apparently perjured himself in an effort to convict the accused.

I suspect something worse than police incompetence may be responsible.
