I am continually baffled by the "logic" behind laws and the justice system.

If corporations are people, then how can they be bought or sold considering the 13th amendment?

How can money be speech, if the constitution allows congress to regulate commerce, but prohibits it from abridging speech.

It just seems like in a common law system we're forced to live with half-assed arguments that corporate lawyers dreamed up while golfing with the judges.
