That's because it was nothing on Saturday. Trump sends in the National Guard and they make a lot of smoke. There were 3 or so waymo fires and some cop cars damaged. Protesters were hit by rubber bullets a lot though.
There are military resources available and heightened security around the white house. In a country where children either buy an AR-15 or get shot by one, that only goes so far.
Contrast that with an actively deployed and on guard... guard. Protests in DC will become next to impossible and "dissenting" congress people will be much less likely to ever try to get a photo op while pretending they care about stopping doge et al.
