I gather the protesters want something no legislation can give them, no government can mandate, no mayor can provide, so I guess they will protest until it gets cold again. Of course, I don't mean every single protester, I imagine some of them have some substantive proposals and ideas.
We could make lynching a Federal crime for example, so cover all the lynching that occur in the US each year, thought the penalty might have to wait for the states to exercise their process in trying the accused.
