1). People are becoming weaker and more stupid...some become teachers, some become police. They do not stop being weak and stupid with their new positions.
2). Bad guys are still bad guys...some may be like the guys in item 1, and they get caught all the time...but not all guys are like what is described in item 1.
3). Your safety depends, and has always depended on you, your skill, your preparedness and your cleverness. Nobody is coming to save you. The best they will do is to take a flattering pic of your dead body for the report.
4). Rules are about controlling everyone in item 1 and 2, but as we see, they fail and will always fail. Your safety depends on you. If a rule interferes with item 3, ignore it.
5). Get good at understanding item 3 and carrying out item 4.
