...it's Tucson. In Arizona. In my country.
A car screeches into a suburban driveway, four dudes un-ass the vehicle, including one with a rifle, and they charge the house. In broad daylight. In suburbia. In my country.
Luckily for the homeowner, who was not carrying a gun, he managed to get inside and lock the door behind him, and lay hands on a pistol before they forced entry. (I wonder if he'd been participating in a "What kind of paranoid carries a pistol at home?" thread on Glock Talk or Arfcom earlier in the day?) Despite starting way behind on the power curve, he held his cool and returned fire, driving off the goblins, possibly with one WIA. I'll bet you his pistol will be on his hip when he's mowing his lawn from now on...
In America. In my country. In suburbia. In broad daylight.
There is a third world country immediately to our south that is on the edge of societal collapse. There's a big slump in the landscaping and lawn-mowing industries here at home. Our own economy is, to put it as delicately as possible, fuXX0red. Carjackings, muggings, robberies, and even incidents like this are only going to become more common. And I guarantee you they won't call ahead and make an appointment, either. Speaking from personal experience, when crime happens to you, it happens real fast.
Carry your damn guns, people.
