Person of interest? No such thing legally
At one time it was against the law to intentionally block traffic on an Interstate highway. no more. When the Socialists decide they want to block one and beat the hell out of the drivers they cause to stop they just do it. When the Police arrive They ensure that the rioters remain safe at they bust motorists after motorists head. And they make sure that no motorists tries to escape by making a u-turn, If they do make a u-turn the Police chase them down and bring them back.I saw one video where the Socialists had people stopped on an Interstate while demonstrating to racism and a Black girl was going down the line of stopped cars with a one way lug wrench busting windows.
If anyone ever gets caught up in one of these "protests" don't depend on the Police to help you. While the Police and Socialists don't tag team, they do work in concert. Yesterday, a Freeper, Travis McGee to be exact, posted a set of instructions one should adhere to when caught in one of these "protests". It would behoove one to follow them. Following them won't save one a hospital visit, but they will mean the difference between a 0 to 20 year prison term.
