These will be worse. The 68 riots were semi-confined and harder to organize. They've already made plans to keep this going for the entire summer, the social media makes it easier for them to change tactics on the move (see the surprise raid on Soho, etc....). Also in the 60's, you still had cops that took no shit. You also had WWII, Korea, and Vietnam vets that understood the need for law and order, and had the backing of the citizens and the actual governmental authorities.
Now, the cops are demoralized, and the citizens are either soft or their hands are tied.
Here's the list of major riots in '68 -
