You're being facetious right?
Actually no - I have never heard of a case where an American died in America from the results of a 50 cal rifle being fired...
No one has ever been killed with a .50 cal in the US, (unless there is an incident where the police used one.)
Ted Kennedy's car killed Mary Jo Kopechne .
Killed by .50cal = 0
Killed by Teddy = 1
It's just not a gun that lends itself to criminal activity. This is a solution in search of a problem.
Let's outlaw what IS dangerous - rather than what the liberal birdbrains say MIGHT be dangerous.
