This guy is confusing correlation with causation.
Sarah Palin talks a lot about guns.
Someone uses a gun.
Does not mean that Sarah Palin cause someone to use a gun.
I don't care for Palin, but it is kind of annoying to see people be irrational.
Although, it wouldn't hurt for Palin and the res to tone down the gun rhetoric because I'm sure they have some crazy fans as well.
I guess it's arguable that in a country in which guns are considered by some an important part of the checks and balances it's not surprosing to see someone use a gun as a political expressoins, so maybe in that sense she has some limited responsibility,
