To exercise a constitutional right.

Dick A. Heller, a security guard whose lawsuit resulted in a landmark U.S. Supreme Court ruling favoring gun-ownership rights, was given his handgun registration certificate at D.C. police headquarters this morning. He applied for it last month, a few weeks after the June 26 court ruling, and had been waiting for police to complete a background check.

No word on whether or not this will derail his suit challenging the District's new handgun regulations as unconstitutional.

I'm curious -- if we are going to license guns and gun owners, when will we start licensing printing presses and journalists, or houses of worship and clergy?
