Here is what is crazy about that Luby's case too, Killeen is a military town. It is the community that is the outskirts of Fort Hood, the largest Army post in the world. The whole town is made up of soldiers and their families. But because we aren't allowed to carry weapons stuff like this happens.
In Bosnia, in all the cafe's and pizza parlors and even churches where the soldiers go nothing like that ever happened because the soldiers are carrying their rifles. They don't leave their hootches without them.
Do we really care whether the drug dealers shoot each other? We just need to make sure we aren't where they are when it happens. And that isn't hard to do.
