Why did Light Care? (spoiler)            My biggest question when rewatching the series is if Near is so sure that Light is Kira and obviously taunts him about it, why doesnt Light just kill everyone in the task force and combat Near head on? He could easily just end the communication difficulty with his other associates (Mikami and Takada) and more closely monitor their movements. Is he afraid Near is going to tell his mom on him? (I think hes well beyond willing to kill his family) On top of all that he has the US on his side he could become untouchable.

             I would like to hear the communities opinion as I'm trying to figure out all of Lights blunders. I believe this, and him not thinking it through enough to realize he could study the book instead of becoming a martyr and truly find a way to use the note for good (but that's a whole other discussion).
