Actually, Cruz did. He said they didn't have the right to SHUT DOWN political discourse but that isn't "good sound bites" for people who dislike Cruz
"I will say this: Protesters have no right to engage in violence," Mr. Cruz told reporters in Illinois, also saying the protesters have no right to threaten violence or shout down other speakers. "The First Amendment gives every one of us a right to speak, but we don’t have a right to silence others," he said. "And to the extent these protesters are organized leftist groups, whether it’s Black Lives Matter or Bernie Sanders or George Soros, or some other moveon.org leftist group, they’re simply trying to terrorize political speech." "That is not their right. It is wrong, and we need to stand against it,"
Cruz is a lawyer. That gibberish you posted is lawyer speak.
Cruz showing incredible flexibility but he did not apologize for blaming the victims of a riot.
The simple fact that all this violence occurs when protestors enter a Trump rally should make it clear to even a 1st grader, that if he protestors didn’t go to the Trump Rally and disrupt the rally THERE WOULDN’T BE VIOLENCE.
