Yeah. "Confusion". I'm looking forward to a bloodbath myself. Then to the losers crying and screaming and threatening to sit the election out. Don't be fooled, though, they'll fall into line.
I expect we will see injuries and fatalities as various Leftist factions attack the convention and each other. Chicago police are not renowned for their calm, even temper in the face of "mostly peaceful" (and very hostile) protestors. And they won't have stand-down orders when it comes to the convention areas.
The hotels where delegates are staying? Well boys, you are on your own there. Not enough officers to cover them.
But I would also watch for a false flag attack by a hitherto unknown "Right Wing Patriot Front" group whose members all seem to be FBI informants. They will be the ones mysteriously allowed through the police barricades.
