Sorry, but I believe you both are wrong. The cop did not say that she could not film while inside her home, he just asked that she go inside. She will make nothing off of this.

Yes, a cop has to do what he needs to do in order to feel safe. My cousins actually all got tasered by a cop. Basically one of them was being hand cuffed and like a daisy chain each one RAN up to the cop asking, "Why are you arresting him?" He's a cop, not a friendly tour guide, if you run up on any cop making an arrest you will be tased or tackled.
Personally, I'll take a taser to the chest over a baton to the face and being disfigured for a week.
A cops demands might seem excessive or insane but you have to remember that at the core of the issue, there is a scared man, outnumbered by the community, trying to resolve an issue before the world collapses on him.
