Even if a streamer is a big target, and the police is aware, they will still go and check it out. It’s an inconvenience for everybody involved, but it’s still the best way to go about it. The only thing that can really be done is to track the people making the calls, or I think in this case an email? Anyways, in Germany you can get jail time for doing this, and they do try and track them down.
Sure it does. I hate the police and thousands of their stupid rules, but them temporary cuffing you when they are assessing whether or not there is actual danger is just how it goes. If you watch the video, you can see he was only cuffed for 2 minutes.
in my opinion you are taking a serious breach of personal freedom far too lightly.
