Two assemblymen in New Jersey introduced a bill on Thursday mandating a minimum sentence of at least one year in prison with no parole for those found guilty of playing “Knockout,” according to a New Jersey Star-Ledger report.

Republican assemblyman John Bramnick, who introduced the bill along with fellow Republican assemblyman Ron Dancer, said that “Knockout is not a game. It’s a violent and dangerous act. As legislators, we must ensure that our laws address the newest inception of violence with the harshest possible penalties.”

Knockout is played predominantly by black teenagers who approach unsuspecting strangers and punch them in the head as hard as possible in an attempt to knock them unconscious in a single blow. The attack usually has no other motive than to harm the victim.

There have been an increasing number of reports of Knockout over the past few years, but the scope of the activity is not fully known.

Currently those convicted in New Jersey of aggravated assault, as Knockout is classified, can be punished with a $15,000 fine and three to five years in prison, however Dancer and Gramnick argue that those convicted of aggravated assault rarely serve prison time.

“Randomly punching someone with the intent to render them unconscious is anything but a game,” Dancer said. “It’s becoming a public safety issue and that’s why we need to address it immediately.”
