As someone who's put down rabid animals before, you really don't want to get close. Think airborne blood matter particles when you pull that trigger. If I was one of the people involved in this incident, I would get the rabies course straight away, just to be on the safe side.
While I carry either a .45 or 9, what I have in the truck is what I would chose long before either.
And people need to stay the hell away from wild animals, especially when they are behaving oddly. A deer standing outside of a store is not normal.
I had to tell lots of *expletive deleted*ing idiots don't feed the deer at my last job. Fricking dumbasses would give their kids food to feed the deer from their hands.
