In many cases they did. Even gave you a link to a judge dumping the charges.

No you didn't. I think you're misreading that article. The judge just approved bail for those defendants. They didn't dump the charges.

But we agree: Portland is totally peaceful and there's nooooooooo problems at all!

It's not a binary. Portland has not been the site of a continuous barrage of violent attacks against a federal facility. It has been the site of an ongoing contentious protest, which no doubt has been loud and disruptive and violated various non-criminal laws like the noise ordinances you've mentioned from time to time. But that kind of disruption doesn't justify calling out the military to suppress it.

I think you've formed an inaccurate mental picture of what's been going on in Portland since June. You had violence at the protests in June, which led the Portland PB to sweep in, declare it an unlawful assembly, arrest people and disburse the crowds. Since then, you've had an ongoing protest around ICE - but nothing like what happened in June. But you seem to think that it's been the same, continuous level of attacks against ICE for 100 days. That's not the case.
