Isn't that like saying that guns may be legal but later use of those guns may not be?

Guns are legal but murder is not, so ... yes?

It makes sense to me that recording public activity may be legal but publishing those videos would not be (for example name-and-likeness copyrights).

Or that you'd need a warrant to search those videos and issuing a warrant comes with a one-time key that decrypts the search parameters you specified in advance to get the warrant.
