>>132900414>>132900723>>132900820Taking L's bait was dumb, but all L managed to prove was that Kira is in the Kanto district, meaning that if Light had played it cool he could have avoided getting caught.
His REAL mistake was outright bragging to L that he had access to police information. All this did was make L narrow down the list of suspects to the family members of people in the taskforce.

>"so L suspects I'm a high school student because of the hours I kill people? Big deal, I'll just keep killing people like I normally do so as not to arouse suspicion">"In fact, even after I graduate I'm gonna keep killing people at the same hours for 2 more years so that L will think I'm 2 years younger"Then L would never ever have been able to find a single lead on Light, because the Death Note is a perfect murder weapon and nothing Light did ever connected him to anything
