This needs to be debated in Parliament I think. using Section 50 powers, it appears (some) police forces are trying to create a loop-hole in the law in an attempt to infringe upon people's right to film a public space. Basically if they get complaints of alarm and distress (including their own staff apparently) then they can demand your details and insinuate your are or are about to be guilty of a public order offense. Whether any forces have done this I honestly don't know. Hopefully the following video will explain things a lot better than I can..
Whether or not I agree with the approach of the person filming, I find this officer's apparent understanding of the law regarding filming in a public place to be absolutely dire. No crime was committed or intended by filming that building. Don't go filming private property? Dude, whatever station you're at..I think you REALLY need to be spoken to about this because your head appears to be in the clouds and unwilling to accept you are wrong. I doubt very much a judge would take kindly to your behaviour irrespective of your interpretations of the law..
Shit car. Ford = Fix Or Repair Daily
Piece of crap.
