I think this is going to be something that is markedly different in the US to the UK.
In the US, you have the first amendment. Indeed, if you google this, you will more often than not find it described as 'First Amendment Auditing'. So there is a clear reason to believe that this is a right in the US.
In the UK there is no such thing. And whilst it isn't illegal to do this, practical reasons are going to make this counter-productive very quickly. All in all, over here, the whole thing has a massive negative expectation.
I suppose if you concentrate on filming the police - or anyone whose job depends on reacting in a proportionate way then you are more likely to get away with it.
Your problem is going to be from the public.
I have never lived anywhere in the UK where this would not be seen as an overt hostile act. And depending on where you are, it would range from 'unwise' through 'asking for trouble' to 'taking your life in your hands'.
