Cameras around your home are important. Awareness of your surroundings is important. Acting in the face of danger is important. This incident hits all of these points, and this homeowner seems to have done a fantastic job in stopping these two bad guys before they even got into his home.
This is a quick one, but a good one. Pay attention to the fact that the homeowner also backed into his garage, something I try to do as well, because it allows you to leave more quickly vs. having to back out.
