I'm sure an investigation into this particular case will surface what kind of warrant (or other legal document) they were carrying out and whether whistling along with police carrying out their work was interference or not.
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!
You seem to have difficulty with English, maybe its not your main language. What part of the warrant type being immaterial for third parties having a right to film the cops was difficult to understand?
