One of the unfortunate facts in any society is that there are always a few violent psychopaths. Fortunately our society has developed a relatively effective means for the good people in society to protect themselves from the violent psychopaths. The most important aspect in any defensive situation is awareness, you must be able to identify a potential attacker. If you’re able to identify your potential attack soon enough you can usually avoid them entirely.
To facilitate identification and, hopefully, avoidance our society has taken as many violent psychopaths as can be identified and issued them special costumes and badges. Upon seeing an individual wearing one of these official costumes and badge you should do whatever is in your power to avoid contact. If you are unable to avoid contact there is a high probability that one of these violent psychopaths will attack you with a blunt weapon, electrical discharge device, or a firearm. They are also prone to firing upon canines so take extra precautions when walking your dog.
