It’s a big club and you ain’t in it https://youtu.be/Nyvxt1svxso
It's all just the oligarchs fighting for who gets to momentarily sit at the top of the pile.
So, I agree with what you're saying, but being realistic, citizens can't really change anything in a modern democracy. Doubly so if any of the magic words can be invoked in relation to the thing they are trying to change ("terrorist", "paedo", "organised crime").
And they absolutely can't change anything in relation to the security services - I seriously wonder if even the government could change anything there, or if the security apparatus really is
Until they decide otherwise.
