fortunately this isn't true, because if it is true, it is also true of cops.
free people can still follow other free people on public streets (thank god)
To an extent. But I'm sure if someone were following you and you asked an officer for assistance, he can within his rights stop that person and question them. Cops are granted that authority, which is why it's illegal to impersonate an officer.
Stalking comes to mind when making the claims of having a 'right to follow'.
It's also not reasonable in this case, because he did more than simply follow the guy, but by his own admission confronted him and demanded answers. Given he's not identified as an authority figure, with a badge, marked car, etc, it's bordering on impersonating an officer.
