You can withhold paying your federal taxes from your paycheck. Most people don’t because they don’t want to get stuck with a big tax bill in April with no way to pay it if they spent that money or lost it on a bad investment. if enough people all did that at once, regardless of state, it could put a big financial burden on Trump. The government heavily relies on this steady source of income, and unless you make a lot of money, you are probably getting a federal return every year, which means you gave the U.S. Government an interest free loan of sorts.
Not all the protestors are involved in criminal activity. The news is constantly reporting that 95% of the crowd is peacefully exercising their right to protest, but a small minority of people use the situation to their advantage and cause chaos. The media then reports on these (accurate) instances of violence and then right wing talking heads run away with that and paint the picture that everyone is looting and rioting and attacking cops.
It’s also a known tactic to have provocateurs incite a riot so that the people in power can use it as an excuse to crack down on an otherwise legitimate protest.
