After 100 days of dissent in Washington, the boundaries between cities, states and even countries have dissolved as protesters from Hong Kong to Portland to D.C. swap tactics, share strategies and ping from one demonstration to the next.

The protests after the police killing of George Floyd have developed a language and shared culture as daily demonstrations become a fact of life in cities across the country. Enraged by the backdrop of police violence and racial inequality that plays out in graphic videos depicting police brutality against Black citizens, protesters have developed new means of resistance experts say may change protests in America forever.

Marches have grown more confrontational — cornering politicians in their homes and heckling strangers as they go about their lives. Protesters have embraced mobility and taken to participating in demonstrations far from their hometowns. Some fly, some drive — some have walked for days.
