Would Rick Santorum be in favor of undocumented aliens carrying guns?

Apparently Rich Santorum’s view is that people in the WalMart massacre were soft targets, and that, had they been carrying guns, they wouldn’t have been such good targets because they would have shot back.

Apart from the obvious stupidity of the remark (as we heard yesterday, the gun-carrying Texans turned tail and rabbited out of the area), one wonders if Santorum would be in favor of undocumented aliens carrying firearms to protect themselves?

If not, why not? Or does he feel that only white citizens can engage in self defense?
