While it may be worth it to investigate the situation and there may some blame on the officer, then the allusions people are making (perhaps not you) are completely out of whack.
I'm sure it's inconvenient if your party or candidate lost the presidential election, but you shouldn't turn to lying for retribution.
I would like to see any situation where an average citizen could kill somebody in a similar manner and be given the benefit of the doubt. Because "He may or may not have been armed, I don't really know because I couldn't see" would not fly in any US court for any other random civilian.
I could also say "there is no excuse for you to not understand why ICE did what they did". No point in these judgements, they don't help your argument.
The entire protest isn't a plain protest. They could do their whistling and marching on a public square, yet they walk and whistle along with law enforcement. (I guess the new way to rob a bank would just be to walk in there with the guards, but say that you're protesting and talk about the letters of constitution?)
Also they're not law enforcement.
There is also no fixed radius. E.g, if there is a police op in one apartment, you are filming in another, but there is a wall in between, then the distance is miniscule. If you're walking along with the officer and filming the op as it happens, then you are in the radius. Even worse if you're also whistling.
ICE / DHS / Border patrol aren't US police, of course - they are immigration enforcement agents with more limited powers despite assertions by the current US federal administration to the contrary.
I'd say, simply don't bring a gun to a protest! As then police won't need to do split second decisions about whether you are using lethal force against them or not.
Though back to filming, while it's legal to just film a cop, then it may not be while an operation is ongoing. If you film the operation in quiet then I guess it's up to debate whether that is interfering with police work. But the protesters were also whistling along with the officers, i.e, giving away that they're there, etc.
As far as I know, they are also first and foremost deporting illegals who are criminals to begin with.
Most of the warrants being used in the minnesota botch job are the Karen warrants from what can be found anyways.
If you know who was going to be captured and how this was only a "Karen" warrant , which doesn't constitute non-interferable police work, post to any source!
Also, why even "protest" at these events when the people targeted by ICE haven't determined to be illegal immigrants? They can just present their basis for legal immigration and be done with it.
