Cops Fear Violence Against Flash Mobs So let me get this straight, because alot of these flash mobs happen to be below the age of 21, which is just an arbitrary legal age, you don't have the right to defend yourself against them? Insanity at its finest! The flash mob participants aren't the real criminals, no, it's the gun owners that want to defend themselves. The way we define 'children' is purely a social construct, unlike race or sex which is a biological reality (thats a discussion for some other time). They arrested two flash mob participants, one in St. Louis, the other in South Carolina. One was 5'11 186 pounds, the other was 6'2 212 pounds. One was 17, the other was 19. These are not 'children', other than the fact that society says they're children. But physically, these are full grown men. After puberty, they're no longer children. In fact, I would go out on a limb and say that those two 'children' referenced above are bigger and stronger and meaner than alot of 30 or 40 year old men. Our perception of what a child is is way out of line. Hearing the captain talk, you would think he was talking about a bunch of rambunctious first graders (6 or 7 year olds, real children) not a mob of violent teenagers bigger and tougher and than a lot of legal adults.
