Actually in most public places there is no reasonable expectation of privacy so quite a few of those laws will not apply. It's not illegal to record someone in a public venue, it's illegal to publish videos or pictures of them for pay without first obtaining a release. I can record as much video as I want of a park and put it up on youtube and never have to get a single person's permission first. But if I try to sell said footage to a commercial company then I do.
