Even as it approached midnight in Washington, DC, earlier tonight, protesters were still out in large numbers in the national capital.
At least one military helicopter was seen flying overhead and hovering in an attempt to disperse the crowds.
The helicopter was seen making slow low-level passes, using its propellers to kick up strong wind and debris. The tactic, known as a show of force, is commonly used by the US military in combat zones overseas to drive targets away from a specific area.
Protesters responded by raising their fists aloft in defiance.
The city curfew went into effect at 7 p.m. local time.
