No, you're on track, and that opinion was also voiced on Websleuths.
Over and over, we see Geragos faced with something that is damaging to Scott, and he invariably reacts in a way that makes whatever it is seem very glaring, very big, very memorable. I'm sorry, I have no business judging this hi-falutin' lawyer, but I just don't see any sense in his doing that!
This college friend statement was pronounced by BROCCHINI, of all people, to be NOT CREDIBLE. Why not let it go at that? And then remind the jury in closing arguments that BROCCHINI didn't even believe the tip, so they should just forget it? It was apparently a very weak tip, something even the prosecution thought not worth using, and here is Geragos making it seem like it was some big, significant thing that this college friend said.
As usual, I'm slow to catch on to some things, but I now realize that this is exactly as others on here saw from the very first: it is just this week's "bombshell", just part of a technique Geragos is using to hoodwink everyone. Just tabloid hyperbole!
In my opinion, the tip was considered to NOT be credible, because it was phoned in AFTER the bodies were discovered. Now if the tip was recieved before the discovery of the bodies, it would have been considered in a completely different light.
