Yes, to control gun violence you need more law-abiding citizens carrying. That's why in Aurora they foud that Holmes went to 3 movie theaters first until he found the one where you couldn't carry inside the theater. He just wanted to kill-not BE killed himself. Chicago has the toughest gun laws in place and their murder rate is among the highest in the country. A killer/robber/rapist would think twice about breaking into a house if he thought the owner had a gun and he'd get killed.
