Correct. The story bouncing around on the internet and that has also been reported on at least one cable news show is that Zimmerman was a drug informant for the Sanford PD, and has been since the the PD dropped the assault of a police officer charges against Zimmerman.
That is why the investigation of the shooting was handled by a drug enforcement officer from the Sanford PD rather than a homicide investigator.
Sanford PD tried to protect their informant
Not surprised. The police are so depraved. Send a drug officer. Brilliant. Protect their drug informant. Great. You know why the police focus on drugs? So they don’t have to deal with the real violence, so they can score cash, too. Bullies.
