You have just explained why Wecht and Stern get along. Like minds.
I think Wecht is on Team $tern because he (Wecht) did a half a$$ed job on the Daniel Smith autopsy part deux; and he knows it. He probably took the 'job' thinking run of the mill, Hollywood kid o'd on something...slam dunk, $80,000 fee (and a trip to the Bahamas...it gets cold in Pittsburgh in the fall). But now, he can't backtrack and say...'oops, wait a minute...maybe we should do x, y, and z' for further info.
