Star Trek the Next Generation, Season 6, Episode 22 "Suspicions"

I call BS. In this episode there is a ferengi scientist who makes some kind of new super awesome shield so you can fly into a star. Other scientists don't believe him, probably because he's a Ferengi. So they do a test and some other scientist flies a ship with his shield into a star, he gets all messed up, barely makes it back to the ship, then dies. Ferengi man says no no no, not my shield, sabotage, my shield is awesome, I'll fly it again myself. Crusher says no, no one else flies the ship into a star, too dangerous, forget it. Immediately after the ferengi guy gets killed. They find he's holding a plasma whatsis that made him die, everyone says well he probably killed himself. Crusher says no, he didn't kill himself, someone killed him. Picard says well, we don't think so, and you can't autopsy him because his family says no, what's more, if you want us to investigate this, you have to find some evidence. WHAT? Dude, even if EVERYONE thought it was a suicide, there should obviously be an investigation. No investigation unless the Doctor can find evidence? No investigation at all by security? That's crap. POLTFAIL.
