[Closed] Undercover (With Spoilers Hopefully))

Can anyone explain the last episode? Twitter has no idea either...
The judge deserved to die (Peado?) Michael killed him...Rudy was taking the flack but not squealing about Michael.
WHY all the undercover cloak and dagger stuff for 20 years?
How has shooter in the woods got off even though the journo was there taking photos the whole time and that the high level politicians have been carted off?

Seems like one of those series (Lost, Homeland, 24 and House of cards) which reels you in and never actually concludes anything.
