Answers to some of the points made here:
- I deliberately left out the location as I do not see that it was relevant to how I was treated, but it was not in London. In any case, why should it matter?
- I'm disappointed that so many of the posts here are almost giving a free pass to the police and 'I don't see a problem that your rights were infringed because it makes me feel safer that the authorities are "doing something", after all, the police wouldn't have assaulted you if you weren't doing something suspicious, and who's to know you weren't a wrongun, it's just part and parcel of the world we live in, etc'...
- If I was up to no good, I could very easily walk around with a camera hidden in a cigarette lighter, watch or pen and get all the footage I wanted without drawing attention to myself.
- It's either perfectly legal to pan your mobile phone around in a railway station whilst in a video call with someone to show them your surroundings or it isn't.
- As already mentioned, it would have been perfectly fine if they'd walked over to me and politely asked what I was doing and I would have been happy to engage with them.
It's seems to be that for many people here to accept that despite not being obviously immediately threatening, the police can use force to stop you without announcing themselves so it's perfectly normal to be expected that from time to time despite going about their business can find yourself being having your arms seized by officers if you're walking through a railway station doing nothing more than having your phone out and demanded to account for yourself, and anyone you complain to for relief says 'Well, it's your own fault, you looked like you were probably up to no good'.
Unbelievable...
