To be fair with Haibara and her tingling BO sensing, she is releaved from a lot of stress, thanks to Conan and co. It began after the Halloween party case and slowly disappeared. If we think about teh train case, she was basicly confirmed dead by actual BO members (or as Conan told her). She can feel at more ease.
But despite this I too miss her sharp sense, I mean, Vermouth IS Vermouth after all. I can't believe her Vermouth sense is totally gone.

Not after how she acted in Vermouth's first appearance and in the Bus Jack case. I can accept that she can't sense anything from Bourbon, since he is a grey character, rather than black, though.
Anyways, I think this was a very good case overall. The murder-thing was okay, an old trick, but the weapon was interesting. I mean the fact how it was put together. I really felt sorry for the murderer.

That mean pickpocket! >.> But to be fair, one should never lock a child in a car alone.
I wonder what's Amuro's plan now. The best trap for Conan would be the good old Ran-hostage thing. If anything, then manipulating Ran or Kogoro would be a piece of cake for Amuro, the rest is up to him.
