There are unfortunately hundreds of examples we can and should be aware of. The bottom line, no person should feel threatened or face a life taking situation, without having the power to have an input on the outcome. There is an old saying I believe the SAS use, "Bad people do, because good people don't". I change it to read, "Bad people do, because good people cann't/don't". Life is to precious to just allow a moment of stupidity give it away. The sad truth is, there are way to many who depend upon the "sheepdogs" (us) to be there. Train as if your life depends on it, because if one day it does, then is not the time to learn.
