Solidarity denotes the unity and mutual support among individuals with shared objectives, crucial in protests for reinforcing collective resolve. Protests are strategically held in high-visibility, disruptive locations to maximize impact and draw public and institutional attention. This disruption compels acknowledgment of the issues, leveraging collective action to catalyze societal and political change. In contrast, low-visibility protests are often ineffective as they fail to generate sufficient public awareness or pressure for change.
This is effective in areas that permit it, particularly blue parts of the US (from an American perspective). You have to be more careful in red areas. Disruption is generally some kind of infraction. Although protest in general is constitutionally protected in traditional free speech zones, any small breach of the law will be met with the excessive force of the law.
