I'd trust a Sikh with a weapon before I'd trust a DUmmy.
By a country mile.
My knowledge of sikhs is based on the fact that when I was younger my father's church was literally just across the road from a Gurdwara. The sikhs there were some of the most friendly, charming, pleasant people one could hope to encouter. Strong sense of community, hard work, and personal responsibility.
I would feel far safer walking down a road knowing that a sikh was nearby with a firearm readily to hand.
