This is really un-usual of smashed rear door glass of a SUV flied over two seat to the leather box next to driver seat.  

If I were you, I will agree with the estimator, when the estimator mentioned the "bad guy" openned the door and tried to open the box with wahtever tool that broke/scratched the leather box.

I do not think your challege to the estimator can reticfy your case but accerlate argue between both part. Report the result and do not guess everything, ask ICBC what do you get before the body shop to do anything.

I do not "trust" body shop becuase ICBC is the Master of while body shop is the Slaves.
