I find it comical your beat officers don't have guns, honestly. Because I guy with a tazer really isn't that scary.
Now, from what I've read, police have substantially more rights to stop you and question you without reason. And more so with how they handle photographers especially.
Our beat officers don't need guns, that's why they don't carry guns. Tasers would be a great deterrent, they're not vital, but I imagine would be helpful especially when dealing with someone armed with a knife or other melee weapon. We have little gun crime here, so what gun crime there is can be responded to by specially trained armed units.
Stops on foot for no reason are rare, only happening if the person being stopped is acting suspicious, or is in the right area and fits the description of someone suspected of being involved with a crime. If you have nothing to hide then you shouldn't have a problem.
I've only ever been stopped and searched on foot when i've drawn attention to myself for other reasons, and i've never seen or heard of anyone acting normally being stopped randomly in the street.
I've had a few routine stops while driving, but only when there was a reason to pull me over anyway (brake light out, ratchet straps loose, etc). If everything is in order you're on your way again in a few minutes, so no great hardship.
As you probably know, U.K media has a bit
too much freedom and likes to think it can do what it likes *cough* phonehacking *cough*.
I don't blame the police for being tough with 'big' media photographers who try to push through barricades and ignore what officers have told them just to get a good shot.
It's the same with amateur photographers at demonstrations and riots, if you go where you're not supposed to go, you'll likely get nicked. On the flip side, there are probably cases where cameras and phones are confiscated without clear reason and 'censored', or broken intentionally or unintentionally in the case of demonstrations and riots. Thankfully this behaviour is the exception, not the norm.
There have been more than enough photos and videos of police brutality against photographers and others to know that it certainly happens, but again, thankfully these cases are the exception, not the norm.
So the general idea is that if you don't act like a muppet or break the law, you won't get stopped or arrested. 💡
