Through a combination of protesters’ vigilance, mayoral leadership, anti-violence interventions, and de-escalation by police, Newark managed to avoid the violence that marred other cities’ responses in the initial burst of protest after the death in Minneapolis of George Floyd.

That team, aided by a resolve among protesters to prevent widespread looting and vandalism, helped prevent all but minor problems and arrests in the first volatile weekend of protests.

A handful of businesses quickly agreed to a live-streamed town hall to discuss ways to increase inclusivity. As a result, a prominent host of popular drag shows was ousted for racial discrimination and the business chamber dropped the neighborhood’s nickname, “Boystown,” from marketing materials because it is not inclusive. The Drag Council has also raised tens of thousands of dollars in cash and supplies to support Black- and trans-led initiatives.

Over time, the participation of dozens of unhoused and housed queer and trans youth provided opportunities for social service outreach, including a mentorship program that paired youth with older queer and trans participants who offer friendship and emotional support.
