Being (knowingly) filmed constantly is extremely off putting to lots of people. Protests are extremely volatile environments, and often a small number of people in them are there to cause trouble. Protestors often equivocate attacking the government as attacking the police (sometimes reasonsably, as the police are effectively a state instrument). It's quite difficult not to create an us versus them attitude when some people in a protest are throwing projectiles.
