We (most of us) take it for granted but I'm pretty sure quite a few people are scared to death, dead man walking due to drug deals gone bad, extortion, blood feuds, kidnappings and so on. I'm sure super rich people have these conversations, just we discuss finding a cheap apartment.
My view is that if someone wants you dead, it's just a matter or time, or price. Maybe the Pope and POTUS are out of reach, the rest if you can't finish them with a handgun you can with an Ar-15.
