Why? That's unequivocally constitutionally protected speech. Why is our tax money being wasted on this?
They're "investigating", presumably with data gleaned from arrests and CIs; you have a right to speech, and a right not to be prosecuted for speech, but a much, much narrower right not to be "investigated", collapsing to ~epsilon when the investigation involves data the FBI already has.
No. According to the latest reports, while searching for ICE vehicles, the protesters are unlawfully scanning license plates, which strongly suggests they are receiving insider help.
There is nothing unlawful about scanning license plates. You are allowed to photograph them in the same way you are allowed to stand around writing them into a notebook if that activity is your idea of fun. Where do people get these ideas?!
I think the idea was that they were getting people associated with Minnesota DPS to do lookups on the plates.
Why would that even be necessary? They are almost certainly just contributing confirmed ICE plate numbers to an Excel file and then checking against it. Low tech and simple. This “criminal insider” angle is just building a bogeyman.
I don't think it's a real thing, I'm just saying that's what the claim is.
