The difference between the two videos seems to be that in this one, the cop didn't care that he was violating rights and continued on with the arrest, thus pissing you off. In the other video, the cop realized he was violating rights, and backed off, thus pissing you off, because who the fuck does this punk kid think he is?

They are literally identical situations, as far as the law is concerned. And if you're not breaking the law, you're not breaking the law, and you shouldn't get harassed.
