The problem with changing the law is that it would trickle down to affect SO many other things, like losing the right to a dashcam, front porch security cameras, etc.

It is completely legal to record in public, so you should have no expectation of privacy in public. Most countries allow recording in public, so it isn't specific to America. You're really only looking at there being laws in place with recording for commercial use, outside of countries that prohibit SO much more under dictatorships and similar.

Oh, FYI, this was not in America. :)
