Which situation exemplifies unlawful assembly?

Unlawful assembly occurs when a group of individuals gathers in a way that disrupts public peace or violates the law. In this case, a crowd protesting a cause without permits and blocking travel ways clearly demonstrates unlawful assembly because the lack of permits indicates that the assembly may not have followed legal requirements for public gatherings. Additionally, blocking travel ways contributes to public disorder and creates safety concerns, further solidifying the situation as unlawful.

The other situations involve gatherings that are either permitted or conducted peacefully, which are typically protected under the right to assemble. A group conducting a demonstration with permits or a crowd gathering for a legally permitted event complies with the law and does not pose the same risks to public order. Similarly, an organization discussing community issues is typically a legitimate and lawful gathering that does not inherently disrupt public peace.
