to give a little perspective for Portland specifically, the PD has been ordered not to work with the Feds. The PD was charged with keeping the streets around the fed buildings under control = which they have not done, or at least only done on few occasions and then only after extended hours of attack on the courthouse (generally after midnight).
So what’s to prevent a crowd of 10,000 surrounding a fed building, burning it to the ground and killing all inside, because the feds can’t come out of their ‘yard’ to defend the building or will be killed trying to egress?? And how will this translate to, say, military bases or federal office buildings? What can of worms does this open?
Attempting to overrun military bases will probably end badly for them.
