I R CSI!
PS, that is the coolest coolant (pun intended) resevior ever! Holy jolt cola bottle batman!
As posted prviously Endo is working on his own bike a soon to be stunter based on a Kawi 600 with an R6 rear end (seen above). Anyways, we hadn't been in the shop for over a week (started electrical), we got back in on Tuesday. And when we got there we found an interesting dent on Endo's tank... that wasn't there when we left Friday.

As you can see it is characterised by 2 small indents indicating that it was either hit twice, or with an object that has two points on the end. We asked around to see if anyone had seen anything... no one had. Talked to Dan and Brad (instructors), but no one (should) have been in the shop.
Endo is planning on sanding down and custom painting the tank (which actually has several dents in it already from a previous owner) so he was not too too upset. We basically let it go and went about our business.
Towards the end of the day I was talking with Endo near his bike when one of our classmates came over and got a little lippy (translation he stood there quietly). I picked up the nearest large blunt object to threaten him with... which just happened to be the jack arm for the jack under Endo's bike. And made the appropriate threaten movement. When something caught my attention.

The end of the jack arm is notched... and the notches line up exactly with the dent in his tank. Now, we don't know who did it, but we know how it was done.

Brad (instructor) mentioned that he was going to have the tank removed and that dent filled in at cost to the school, something about making a point. It'd be really cool if it happened, but not really that important I suppose. I'd much rather find out what fuckwad put the dent in there in the first place.
Of course I'm generalizing from a single example here, but everyone does that. At least I do.
