The part that is, is that Worf gets involved with troublemakers basically opposed to everything the Federation and Starfleet stands for, further violates his Starfleet oath by committing an act of domestic terrorism, and it's played off way too easily.
Of course, that's par for Worf's course... It's just that this time around, the troublemakers opposed to the Federation and Starfleet aren't fellow Klingons. But Worf must feel invincible, having broken UFP laws and Starfleet regulations left and right and having left a mile-long trail of bloody corpses, and still having come out of every possible inquiry smelling of roses.
