S1·E9 Shaking the Tree

Pursuing another line in the bombing investigation, the team raid known drug dealers with the hope of shaking out much needed information. One raid goes wrong when Lochie, the Senior Sergeant, is nearly shot by a terrified dealer. During questioning, it's discovered the frightened man was robbed - and his young sister assaulted - by some very dangerous men. It all points to the bombers but the dealer will not talk - no matter what. He's scared to death of the men. It's a frustrating dead end for the team.
