I saw a few of those, when we were in DC.
A/C of interest possibly related to protests/riots:
VM767 is tracking near Washington DC at 1,700 feet, It is a UC-35C. Unclear at this moment if it is doing some sort of survallience (via the sometimes equipped WF-360TL imaging system) or being a troop transport.
