My point is, let's not kid ourselves. Already in North American airports we've had a guy tasersd to death and then a Canadian who was rendered to Syria. Scary stuff.
Don't believe for a second that we have it differently from any other country. What you see "over there" is rapidly coming "over here". No longer do you have your friendly local police patrolman or government agent.
It's all gone militarized, black face masks, SWAT-style.
Tag 'em and bag 'em, tasers and zip ties first, trial (maybe) later.

The new buzzword is: Pain Compliance.

Check it out, even the transit police in Vancouver are tasing people who show the slightest bit of resistance.

Not to go off topic but I'm making the comparision that all types of security, including in airports, has become militarized and more extreme.
