Most likely. There is no way that he had time to reload. This kind of attack is becoming more common because of these weapons. I don't get why people do not want to outlaw these guns.
These bears come into our neighborhoods and try to mooch off of honest working people. They don't work like illegal immigrants. Have you ever seen a bear on a roof or cutting grass? I didn't think so. I bet the staple gun was stolen.
