There is a safeguard under our First Amendment for political protests. However, that safeguard does not extend to protests that lead to assault and battery (or worse) of other protesters, passersby, police officers, or news reporters.
Most recently, during a political rally in Chicago, for one of the Republican candidates, Donald Trump, a protest erupted. Thousands of protesters and the candidate’s supporters faced off in what started as a mere disagreement in campaign policies and slogans and ended in a “free for all.” In the aftermath of the protests, four people were arrested. One of the protesters faces one count of felony aggravated battery against a police officer and five misdemeanor counts of resisting arrest. If his main purpose for attending the rally was to go to jail, then he succeeded.
