There's no constitutional right to go around with guns if you bring in a law to say so.

There's nothing in any constitution about it. The nearest is something about the right to be drafted into an army or militia to defend The USA. I believe it is called the right to bear arms.

I know you are living in a lawless third world country but the democratic majority of your decent citizens want this criminal activity stopped. Take lessons from democracies and work as they do.
