240 is on the money.
I felt like shit reading this headline this morning... We had just discussed a random grocery store shooting... and it happened last night. it would have been more than 2 victims if a cop hadn't shown up that quickly.
Last night I was out for dinner, quick bite on the way... two youths with thick ass coats bypass the line and power walk up to the register with some serious anger in their faces. Instantly I stepped to drink refill station took a flank position with glock in jacket ready to center mass them from 3 feet away with the counter as cover, should anything but a wallet emerge. They pulled out a receipt and yelled about something, they were given refund and food, and their rude asses left without incident. The goofy smile never left my face, standing there with a medium cherry coke in left hand and glock 27 in the other, pointed at them thru my coat. Simple preparation. To everyone in that place, I'm just another schmoe eating my burger with mayo and mushrooms, slurping down a drink. But if a gun appeared, then yes, I was in a strategic position to put 11 bullets into the 2 of them from three feet away with surprise on my side.
paranoid? I dunno... If we were in a war zone, it wouldn't be paranoia. And given X amount of murders happen daily in the USA, some would argue it's a low-grade warzone in some neighborhoods. It doesn't make me stressed... if anything, I feel peaceful and relaxed that I'm able to feel safe while eating, not just "i sure hope that never happens to me". Maybe 1-2 times a week, my spidey senses will go off like this, I'll put on a goofy smile and maybe sidestep to cover while my left hand clumsily holds the bag (remember, clumsy and goofy is very disarming) while right hand readies under clothing. It's always nothing, and I always happily move about my day. I even nodded at the 2 angry looking dudes and remarked about the fries in this place. All was well. But one day, which I pray never comes, if some random idiot starts off'ing people, I will have the best chance to surprise them and stop a forcible felony.
