The government of Denver issued a decree that prohibited the private ownership of bump fire stocks. It turns out that the law was unnecessary because every bump fire stock in the city was apparently lost in a boating accident:
Denver Police police last month invited city residents to turn in any bump stocks in their possession but Denverite reports that none have been handed over.
The ban on bump stocks approved by the city council in January was considered largely symbolic. Denver had previously banned the types of semi-automatic rifles that can be modified with bump stocks.
I’m sure other governmental bodies will enact similar legislation and see similar results. It turns out that gun owners are shitty boat drivers and more often than not they end up losing their controversial firearms in bizarre boating accidents.
If nobody owns one why bother banning them?
