Via Radley Balko, here's a pretty disturbing paragraph from the WSJ about the recent attacks in Mumbai and India's gun control policies:
At about 9:45 p.m., two gunmen, slender and in their mid-20s, ran up the circular driveway at the entrance to the Trident. They shot the security guard and two bellhops. The hotel had metal detectors, but none of its security personnel carried weapons because of the difficulties in obtaining gun permits from the Indian government, according to the hotel company’s chairman, P.R.S. Oberoi.
Now, it's quite possible that these employees wouldn't have had the time/skill to ward off the attackers with whatever guns they were given, but it's hard to argue that hotel employees carrying guns would have made the situation worse.
