Personally I'm on the Israeli "side" but that guy is doing nothing wrong whatsoever. He has every right to show support for Palestine and its people (something I agree with - I take issue when these people show support for Hamas and spout antisemitic views, which they can often do).
I didn't get through that whole video but it doesn't need to be 6 mins long. Here's how it should go, time stamped:
0.01: copper knocks on door
0.02: Hello copper, am I doing anything illegal?
0.15: after a friendly exchange, copper explains no, you're not doing anything illegal.
0.30: after another friendly exchange, you politely tell copper to fuck off your property and catch some real criminals.
0.35: kettle on, settle down for Antiques Roadshow / Netflix / whatever.
Absolutely fucking sick of seeing videos of dickhead coppers playing games with dickhead GoPro enthusiasts.
