Hes an asshole who happens to be carrying a camera. And then when people get irritated, he makes it out as if the camera is the primary cause.
(Street) musical performers distract me though.
People don't feel threatened by surveillance cameras because they think no one is watching that video 24/7 and it is used if something goes wrong or needs investigation.
Where as some random guy suddenly walking in with a camera makes them think that person must have some immediate and possibly malicious intention.
However I was only trying to explain the behaviour of the people.
