Information operations directed at Hong Kong

An analysis of information operations that caused and more importantly sustained the protests would be equally interesting.

I am 90% certain that foreign intelligence services or service are actively involved in the riots.

Probably funding it at least partially and inciting the crowd. Probably have assets in the group of protesters to direct their activity.

I have written before that China has been far more lenient than the US would have been under similar circumstances.

The moment someone had broken into congress they would most likely get shot, at least enough to stop them.

Shutting down an airport would mean spending quite a bit of time at a "detainment camp". Often in warehouses created by law enforcement to hold a large number of people outside of regular courts and jails (See the DNC in Denver).

The protesters are, for whatever reason, hell-bent on forcing China to act in a brutal manner. Any regime would.

While that possibly might be, there are legitimate grievances when you see that many people in the street.

I'd say this is almost certainly not instigated by foreign intelligence services and I'm skeptical they would risk trying to run it. (they probably aren't too broken up about it happening though).
