These self styled "auditors" go all over the country riling people, security, and leos up by filming in public. They hang out on sidewalks, roadsides, in public parks, and enter public buildings. They'll also take video of what they can see of private places, including through windows, from public right of ways.
If security or the police approach; they say they are private journalists exercising freedom of the press, but refuse to show ID or answer specific questions. They are kind of pricks, and are pushing buttons (an old term for triggering) but are usually educated on the law.
The general public seems to think we have a right to privacy in public and hate being openly filmed. Even though we are discreetly filmed all the time.
The police and security think they have the right to demand ID, ask what someone is doing, where they are going, why, etc., and hate to have their authority question.
A vocal minority of cops tend to unnecessarily escalate encounters. Others don't stop them. They will approach people aggressively and / or disrespect them, then use"officer safety" as an excuse.
