Kalani shot the radio for a reason. He had enough good sense and intelligence to know that if Michael couldn't contact them, Datu couldn't know when Pippin's killing took place. He would assume they left long before it occured.

Then Kalani had Burt and Saul "radio" the tower so they could be the one's who learned the radio wasn't working. It was he could say, "Oh, I didn't even know something was wrong. Datu and I left and everything was peachy."

Michael did kind of drop the ball though. Kalani had just given him a status report a couple of minutes before the murder. It sucks that he quickly eliminated Kalani from the list of suspects. His confidence that Datu and Kalani were innocent even convinced me! I actually had Kelly pegged as the shooter. Way to go Michael. If I didn't know better, I'd also believe that Saul, Victor, and Lizzy were dead!

Sarge needs some rest. His brain hasn't been right for a while now.
