It's the nature of the job
> the security services of all countries need to take a chill pill
As an American, I'll state for the record that I think the real problem is that we keep hiring _only_ the sort of person that actually wants these jobs.
I've had enough encounters in my life with cops and others of their ilk who clearly wanted the job purely because it allowed them the power trip they desired.
I'd love to see a mandatory year (or two) of 'government' service after high school with random assignments to community police, military, peace corp, TSA, DHS, park rangers, etc., (with no get out of jail free card for anyone, including the 1%ers). If we had average joes in these positions instead of psychopaths looking to get off on power trips I bet the world would be a better place.
