I can't shake the feeling that Lois is losing a lot of her objectivity this season. She is so focused on being Piea's bestie and being empathetic about her cancer that she's losing sight of the fact that Piea is a stone-cold killer. If Lois got in her way, she would have straight up murdered her without hesitation.
The Mannheims have robbed and trashed the DoD so many times that it's amazing that Sam hasn't been court martialed and the CIA hasn't just gone ahead and assassinated the Mannheim family. Good lawyers can only do so much.
Your trading one monster for another! Luthor and Mannheim. The only difference between the two is that Luthor is more subtle with his deceptions and Bruno is more confrontational.
Clark and Lois are so idealistic that they will ignore that, along with every other crime that they *know* that Luthor committed, just because he's "innocent" of killing Boss Moxie. It feels like Clark is hell bent on keeping murderers on the streets. That's why Lana should send him a bill for the damage to Smallville caused by him holding back on Henry Miller.
