The government says dozens of federal agents and deputy marshals have been specially assigned to combat gun violence and catch fugitives in Detroit. Authorities say the effort is to reduce crime, not interfere with protests against racism or excessive force by police. U.S. Attorney Matthew Schneider says federal troops are not patrolling Detroit streets. Schneider says it's irresponsible to suggest that the government wants to squash lawful protest in Michigan. Earlier this week, police Chief James Craig said violence was rising in the city. More than 500 guns were seized in a recent four-week period.
