If you listen to this clip, there is an important revelation here.
PROTESTOR: “Why are you doing this? Policies are killing people.”
POLICE: “I agree with you, I’m just doing my job…I’m just as over this lockdown as you are mate, but this is my job. I’m not skilled to do anything else.”
The significance here is that the cop is saying his wife is out of a job. At some point, even the police will not lay down their lives at the end of the day. However, here he is saying he does not support this tyranny but it’s the only pay he is getting. This sort of tyranny will go only so far. The main ruthless element that will drive police to kill people is that they are told you are evil. As long as you are POSSIBLY guilty of anything, you will deserve death, despite the fact that the immediate event may more justify the punishment.
This sort of attitude is missing in most of these events. If the police are not CONVINCED of your guilt, then they will flip at the end of the day.
