They will go easy for a few days as they map out where the cordon will be and set up the plan for the checkpoints. Letting people come and go, but strongly hinting that "something is coming" and that if you don't want trouble, stay gone.

They are most likely going over video footage of the riots and will be setting up a cordon and search operation. Once the cordon planning is all set up, the roadblocks, evacuation and tactical door to door operations will last from several hours to a few days.

This will be a critical stage, as they are likely backing off. The curfew was a joke anyway, the real anti-riot curfews tend to be dusk to dawn.

I would be advising people to set up their own evacuation plans, and if they plan on evacuating armed, pre-position weapons where you would want them to be once everything gets locked down. Once they lock down the cordon, people going in and out will be searched at roadblocks and you can bet weapons will be grabbed at those roadblocks.
