Establishes offense of inciting public brawl; upgrades penalty for disorderly conduct in certain circumstances.

This bill creates a new offense for "inciting a public brawl" when someone purposefully organizes four or more people to engage in disorderly conduct (like fighting or violent behavior) at a public event or gathering. It upgrades penalties for disrupting public gatherings: causing such a disturbance becomes a fourth-degree crime (up to 18 months in jail or $10,000 fine) instead of a lesser disorderly conduct charge. The bill also adds a separate offense for concealing one's identity during disorderly conduct to avoid arrest. These changes directly affect individuals who organize or incite group disturbances in public spaces like events, parks, or venues.
