I brought this topic up to point out how valuable it is to be anal about training and approaching situations in high risk-low probability situations.
Many times people will convince themselves that since there has been no incident of something happening that it will never happen. However, this is far from the truth. For example, a person who starts their car each morning gets used to the fact that it will start on the first try. There will be that day in the future it will not start on the first try.
Just like in self-defense situations. We dont know when exactly it will happen, but after a number of times, it will happen. Therefore, for law enforcement, training and protocol is very important. For civilians, the best practice is situational avoidance.
Should you walk outside of your house at night without first turning on the lights and looking out the window? Even though there has been no incident after several years doesnt mean it will never happen. In fact, after a series of no incidents tells me that it might be just about to happen...
