We obviously don't let police "just do" that, and I don't see how this law increases risk here. The other side that people seem to be missing here is that it explicitly establishes a boundary past which it's perfectly fine to film the police.

In many other jurisdictions this would be at the discretion of the officer, if they felt you were merely interfering with their investigation they could arrest you. A law like this clarifies exactly where that line is expected to be. And it's reasonably short enough and with appropriate exceptions that on it's own, I don't see a problem with the law.

Regardless of how one may feel about the sponsor of the bill, it was still voted on and passed by a majority of the legislative body.
