Thousands are marking the fifth anniversary of George Floyd's murder at religious services, concerts and vigils nationwide. In Houston, the Rev. Al Sharpton spoke at a private graveside service. Sharpton said Floyd represented all those ‘who are defenseless against people who thought they could put their knee on our neck.’ Events at George Floyd Square in Minneapolis include concerts and a worship service. Showing continued tension with police, a fake pig head mounted on a stick near where Floyd was slain wore a police cap.
