You're making assumptions with a flawed logic. "If-then-else" thinking doesn't apply (IF I don't go to the ghetto, THEN the hoodrats won't hurt me).
Would a sane person go to Walmart? This isn't going to extremes because we must remember that members of MS-13, Mexican Mafia, Crips, Bloods, Latin Kings, etc are at places like Walmart or the grocery store. The same ghetto rats are robbing and maiming ourside of the ghetto. In fact the new trend around NY shows rats heading into the suburbs for a victim... nothing worth stealing in the hood I guess. It's not absurd to consider this. The trend is increasing, there has been a paradigm shift in the MO of "flocka." No one can prove how rare it is or isn't for a gun to be taken from an unsuspecting person. We assume there are no incidents just because the press doesn't report everything? What I CAN tell you is that if there are six or eight armed gang-bangers, they're going to get the gun if they want it. You can't fend them all off and they're willing to kill or die over something as small as an imnsult.
Many people are trying to paint this in black and white. After 17 years in tactical training with numerous police agencies, FBI, HS, etc, I find that there is no generalization that can be made. We can train a skill set into someone but we can't tell them how the threat will present. The truth is that we can't think of or be prepared for every eventuality. Those who think they can are sadly mistaken. So you don't go to the ghetto. But the ghetto DOES come to you. Who would think a murdering child molester would pop out of the woods in a quiet rural farming community and murder our little bro? Never would have thought it so the family wasn't prepared for it. The biggest mistake in PP is to think something can't happen.
As I've stated before... I support OC for those who do it legally. Just be very careful and always assume the rat is around the corner. That's all.
