New York, April 15 (RHC)-- Protests have been held from coast to coast in a day of action against police violence and racial profiling.

In New York City, some 250 people with the Stop Mass Incarceration Network marched across the Brooklyn Bridge. Dozens of people were arrested as scuffles between demonstrators and police broke out and traffic was disrupted for several hours.

Activists were also detained in Los Angeles after a large crowd blocked a Metro track during Tuesday rush hour.

The protests follow the recent police killings of unarmed African Americans Walter Scott in South Carolina and Eric Harris in Oklahoma. Each incident was caught on video.
