What will the Antifa thugs do if the cops go into seattle in force?
They will kill as many cops as they can, then throw down their weapons and blend into the crowd.
How do I know this?
Because it's the same thing every terrorist organization does and Antifa is no different.
Liberals are like a "Slinky". Totally useless, but somehow ya can't help but smile when you see one tumble down a flight of stairs!
