VIDEO: Cook County Deputies Help Fight City Gun Violence

The Cook County Sheriff's Department is taking extreme measures to suppress gun violence in Chicago with a new Illinois law enforcement strategy that redeploys deputies from the suburbs to the city.

Those deputies are going after people with arrest warrants, often for violent crimes.

"Sometimes it's hard to get a good address. And when we get one we work it pretty hard," Cook County Sheriff's Sgt. Emiliano Valenica told NBC Chicago.
