On any given day or night, dozens of Detroit’s toughest, most street-savvy officers descend on high-crime areas to round up as many illegal guns, drugs and bad guys as possible in one swoop with tactics as simple as minor traffic stops. Police Chief Warren Evans said the death of Officer Brian Huff, who was on a routine call and not working with the program, justifies his belief that police have to “take the battle to the criminals” by hitting areas where crime appears to be taking over.
