Well if it's stabbing or anything like that I'd say it would help prevent incidents.

As most altercations happen in the bar, and take heat outside the bar. If you can't get a weapon into the bar, then you can't use it outside afterwards (in theory) meaning that the fight would still take place, but mano-a-mano, and not mano-a-knifey

(Got to love Canada, we're worried about knifes in street fights, and not guns)
