The video says to think the person is a good person but to be ready. I call Bullshite! Edmond Burke said that the only safety for good men is to believe ALL evil of evil men. That means you should believe that any person you don’t know is capable of ANY kind of evil. Murder, rape, arson, molestation, robbery, theft, ANYTHING! That doesn’t mean to be scared of them, it means to be a good scout and to be prepared. OPSEC! Situational Awareness! Physical and mental preparation! And once you understand these things, practice them: Practice, Practice, PRACTICE!!! Take Marine General James Mattis’ statement to heart: Be polite. Be Professional. But have a plan to kill everyone your meet.
