The curfew and the security measures were put in place precisely to prevent riots from breaking out.
Antifa/BLM will not pass.
They will not be having a very good experience if they tried anything. This is not Portland or one of the Dem run cities which regularly allow anarchists to murder and loot and burn.
We will see if Republican fortitude exists. Planning is one thing, physically stopping the ATIFA and BLM hoodlums is another.
They have passed security before because they know how to infiltrate. What happens when they toss off the sheep's clothing and bare their fangs?
