Don't be complacent. Take this opportunity to make sure those systems really are as tight as they can be.
my gut feeling is that on the whole UK police are quite restrained, profession and well trained. There is also a thorough system for bringing those who abuse their power to account. Of course your average on the street 'bobby' doesn't carry guns anyway.
I've read a few articles linking the British police force to the HK police. While this is probably propaganda it doesn't mean British police aren't accepting job applications from Hong Kong police officers and studying tactics here. Shouldn't they be studying tactics?
What systems are in place? How would they hold up?
There's a lesson here.
Are British police able to disobey a direct order? I had training in that but when the time came I buckled. I find it hard to believe British police are immune to Stockholm syndrome.
People just look at the news here and lump it in with all the other news and violence you see in TV. You're not going to accept it as a threat of that means work. You're just going to think this is Chinese people fighting. No morals. They're not like us etc. They don't see the links. All the emotive media is just pushing people away.
