I mean, it makes sense for politicians to condemn riots, since the alternative, inciting a riot, is literally illegal:
“United States. ... Incitement to riot is illegal under U.S. federal law”
“In criminal law, incitement is the encouragement of another person to commit a crime. Depending on the jurisdiction, some or all types of incitement may be illegal. Where illegal, it is known as an inchoate offense, where harm is intended but may or may not have actually occurred”
