ah … stupid theives are the best kind
if i was the kind of person that steals, and i stole a lap top, first thing i would do is comb thru the files for usable data and immediatly copy it, so that even if i was found with the laptop in my possesion i at least wouldnt loose the data
and af for the comment that “no data was accessed” , i would think that this is something they could easily check, considering ever file has the created / modified / accessed dates in their properties
what more do ou need ? maybe check for temp copies of the files that might be created due to copying to floppy disk or from being printed
if they didnt find evidence of the files being accessed, then id beleive they werent accessed, to pety theif has the skills to clean their tracks that well
