The true reason for this is that there are two (basically) groups of people in the US. The group that is pro gun might be opposed to this, but are not going to directly use weapons to defend themselves unless targeted. And they are not being targeted in this situation, so we don't see that coming into play.
100% - one recent comment by Kevin Sorbo sadly nails it:
> “Is your freedom more important than my safety?!”
> I don’t know you, my lunch is more important to me than you are.
