Police in Portland, OR. know how to deal with protesters that block traffic. When I see protesters blocking traffic causing all kinds of problems, my only thought is, why aren't they arrested immediately? I don't get it. Sure, you have a right to PEACEFULLY protest but to block someone from getting to where they need to go is just ignorance. Especially if they're blocking emergency vehicles.

it makes no sense as to why protesters are allowed to do this.

Well, Portland is doing it right when it comes to arresting people who block traffic. Check it out.
