I do think that the teeth were in the medicine bag which the Rez police chief removed from Harry's office. But the thing we kept asking was - How does the Denver detective have juridiction to execute a search warrant against a law officer in another state? I thought the FBI would need to be involved in that. Also, I question the legality of being able to remove official police files from a police station in the name of that warrant. And finally, from watching an awful lot of Law & Order, I would have thought that a judge would have needed a heck of a lot more evidence than an unreliable drug drealer's eye witness statement.
I did think that Walt did a good job in his facedown with the detective. He didn't give anything away or admit to anything and frankly, the detective was frightening in his vehemence in projecting the angst of his youth onto Walt.
The clifhangar of course, is not only what is going to happen to Henry (although even there I question the lack of evidence for a successful prosecution) but also, will Branch survive? (I hope so as he is growing on me) and who is the real killer of Walt's wife. A smaller continuation will be what the truth behind that burned guy and who shot Branch.
