looting leads to shooting
I believe what POTUS means is that first they loot and then they shoot - meaning the anarchists. And that is truly their MO (modus operendi)
If that’s what he meant I stand corrected. I didn’t read it like that (especially looking at the context of his original Tweet), and I’d bet most people read it the way I did. Frankly, I’d prefer it if he meant that if you loot, you are subject to be shot. That would give people who are destroying businesses and lives some pause. We’ve become a weak society that allows far too much anarchy.
