Sbane has more or less posted what I was thinking... except one thing, why do these happen in your country much more than anywhere else? This is a very serious question so I am eagerly awaiting the inevitable moment when this thread gets derailed into yet another pointless debate about weapons access.
They don't. This is what happens elsewhere. Here in America we shoot the perp dead.

On May 28th 2010, four gunmen entered two mosques in Pakistan and started shooting at a slew of worshipers belonging to the members of my community, the Ahmadiyya Muslims (which the Pakistani government classifies as a religious minority)
In Pakistan, the media broadcasted live images of the gunmen shooting at worshipers while the police stood by the sidelines. The pundits partly held the victims responsible for "provoking" the attacks by practicing their faith while reactions from Ahmadiyya Muslims went unreported. The attacks left the nation divided at best and united at worst — united in disparaging the Ahmadiyya Muslims, that is.
