[Death Note\DC] How would Batman handle the Kira case?

Hm. He would come to the same initial conclusions as L, likely using some of the same tactics. Data analytics, using criminals with fake names on TV, etc.

Once he narrowed down the general area... that's when it would get tough. He would probably realize that Kira was somebody who had access to the police database immediately.  Moreover, he wouldn't be nearly as worried about being able to 100% legally prove who Kira is.

That is, he would bug who he wanted to bug. Threaten who he wanted to threaten. There wouldn't be the same pressure from Light's father, or the need to get clean evidence to take down Kira.
