Have Waller herself be the antagonist, getting frustrated trying to get it through his head that he's upholding a system totally opposed to his overly idealistic vision, but Clark just can't grasp it.

Even better, have 90% of clark's shit get assuaged by "oh actually it's OK because it's legal".

Clark catches an off duty cop shooting a black 17 year old for stealing apples and running away (Clark uses xray vision to tell the kid has a recipt on him)

Clark's article focuses on how the kid didn't steal the apples and the cop should have made sure.

Lois: Uhhh shouldn't you mention that cops shouldn't be summarily executing children for being black under the pretense of stealing? Maybe that the justice system shouldn't create situations where kids need to run from cops?

Clark: Whoa whoa whoa the internal investigation determined that the cop was not racist and had to defend himself incase the kid had a gun. The kid should have worked with the system, not against it. Both people are wrong here.
