One person we can be sure is NOT the leak is Detective Sanchez. He's fiercely loyal and he can keep his mouth shut, even under pressure. Remember when Captain Raydor was interviewing him about the Shootin' Newton case? He clamped his lips together and told her nothing.
Speaking of Captain Raydor (the Raider?), could she be manipulating Brenda out of a job so she could manipulate herself into it? I certainly wouldn't put it past her. The question is whether she is privy to enough of the squad's operations to do any real damage.
