Over-21-year old stabbed at club; will mayor crack down on older miscreants?

Boston Police report two stabbings downtown early Saturday - one of them of a man stabbed while dancing inside the Roxy Nightclub on Tremont Street.

Given that Mayor Menino cited violence as a reason for new regulations barring 18+ events that end after 11 p.m., when can we expect a similar crackdown on all entertainment?
