It's half deniable disruption on behalf of certain parties--note the marked lack of Antifa activities during this presidency, even though the government is almost entirely the same as during the last one--and half an excuse for keyboard revolutionaries to act out their violent fantasies from the comfort and safety of the anonymous mob. It's all smoke and noise, meant to panic the herd into believing that only by removing those people in control for the "correct" ones will we be saved from a life of tyranny and oppression.
