There were too FEW guns here. If a few more people had been armed and properly trained, they could have dropped him before he shot as many people as he did. Maybe before he shot anybody.
I work with a guy who once carried a loaded gun in his car when he went to LAX to pick up his mother-in-law from Germany. He was really sweating it because after he picked up the M-I-L, he couldn't find his car!
