This happened in my hometown, not even a mile from where my dad lives.
The sad part is that it used to be a really nice town-as a kid, I used to be able to walk across the street to go to a friend's house without my mom worrying about me being kidnapped or shot. I could go to the playground down the street by myself.
Sometime in the mid-nineties, this changed. The people in our cul-de-sac started moving out in droves, which was sad because these were all people I grew up with. What was even worse was that the homes were being sold to people who in turn rented them out to people who were, to put it nicely, not quite up to the moral standards of normal, law abiding citizens. Cops started showing up more, because crime had grown. By the time I was in high school, I no longer felt safe walking home from my friend's house if it was getting dark out.
So what happened at that 7-11 does not surprise me in the least. It is what that town has become. What really bugs me is how some people think that this kind of behavior is ACCEPTABLE. In some countries, behavior like that would get them a caning, loss of a limb, or worse. How f***ed up is our society that people think this behavior is okay?
