#and Asbury isnt an investigator by any means

[befuddled-calico-whump]

Is he more the I just need a guy to pin the crime on or more of a I will find who did this and bring them to justice kind of guy?

Kind of a mix? He's not as driven by justice and the need to uphold the law as say, Inspector Javert from Les Miserables, but he's not purely lackadaisical about it either

If he's got say, an unsavory troublemaking suspect in his hands but no real proof, he can pin a crime on them (thus easing the public's mind) and get someone who probably commits crimes anyway off the streets. It's a win-win

That being said, if he truly believes the perpetrator is still at large, he won't just give up and pin it on someone else. That's mostly reserved for cases where the trail has absolutely gone cold.
