» Sergio Sommerville, who said he was a small-time drug dealer in Baltimore, said officers blocked him from leaving the storage unit where he was living. One of the officers said he was with the Drug Enforcement Administration. He was not. The officers said they had a warrant. They didn’t. They didn’t even know Sommerville’s name — though they tried to bluff, he said. They ended up taking thousands of dollars out of a sock kept in his storage unit, and left without charging him.
