Over at Welcome to Williams Lake - they report that WL RCMP Detachment Commander Warren Brown states that bear spray was used in one criminal activity and may have been used in an attempted robbery - see here
As Mr. Brown states in the article - the City of Williams Lake is looking into the mechanics of a "Dangerous Weapons" Bylaws for the City. However, I would argue that without a provincial ban, a local "Dangerous Weapons" bylaw will have no teeth because others' will go to another community to acquire those same "dangerous weapons" to be used back home. In addition - people have used common materials to make "home bombs". Why don't we regulate the sale of bleach, pencils, pens, etc as they can be used in the making of weapons as well. How far should society go to regulate what can be acquired for personal use, in the name of protecting society as a whole?
