Errol Barnes was a nasty, evil, violent, serial-killing thug in the 1995 movie Clockers.
He was portrayed by Thomas Jefferson Byrd.
Much like with Darryl and Rodney, Fresh tries this subject but fails. Errol can be likened to Jake. In fact he's worse than Jake. Even Jake did his acts out of jealousy. This guy is so bad-tempered, he hates humanity and even threatens Tyrone with a cigarette, by trying to stick it in his eyes.
In one scene, Rodney talks about how Errol (because Errol used to be a functioning part of the gang; in reality this is a gang, not a mob family), until drugs made him disabled.
He tries to have Strike killed, when Rodney orders it. However, it fails, when Tyrone gets word of it, and shoots him.
