Armed, dangerous and legal

The recent mass shooting at the premier of the new Batman film is yet another indictment of America's existing gun laws.

The United States has just witnessed the largest mass shooting in its history. Shortly after midnight on July 20, a young man walked into a movie theatre in suburban Denver, Colorado, threw a smoke bomb of some sort into the crowd and began firing guns. The place was packed because it was showing the premiere of the new Batman movie. The young shooter had come prepared. He apparently had with him an assault rifle, a 12-guage shotgun and two handguns. Seventy-one people were shot. Twelve of them are dead.
