The website for tracking these bills [1] seems pretty good though. It makes sense to track bills that might affect protests whether or not they're specifically about protests. (And whether or not you agree with them.)

Summarizing a complicated, controversial situation with a single number is always going to get into disputes about definitions. I'd say don't focus on the count() query.
