Really? Data? Cause and effect?
I've got Ludy's in Killeen, TX (seat yourself), McDonald's in Fresno, CA (seat yourself), and IHOP in Carson City, NV (variable). Then there is the Lakewood Police at the coffee shop in WA (4) gunned down (seat yourself).
I'm not sure what your getting at here. I mentioned that chain type businesses would be more likely to have a mass shooting incident, and you proceeded to give a list of those very places. If you were questioning the data on this, I don't have any to give without searching right now, but it's pretty obvious you'd be far more likely to be shot or robbed at these type of places then stand alone restaurants. Why? Because they are everywhere, and usually always have a high amount of traffic in them.
