(WTOC-TV) Carrie Mills is a retired Atlanta Police officer with 30 years on the job - primarily in APD's drug unit.
Mills is now a union rep for the International Brotherhood of Police Officers. She considers herself an expert on search warrants, particularly no knock warrants, which allows officers to enter a structure without knocking first.
Mills says no-knock warrants helped close a lot of cases while she was an officer.

"If we knock and announced, all evidence is going to be destroyed," Mills said.
