Hi, longtime lurker but had to jump in on this. This forensic guy sounds like the only qualifications he has is an online class in forensics. For one thing, "hits" is an extremely subjective number, most experts wouldn't even use that term or give an exact amount. This "expert" is also throwing around things like there were 6,000 and however many hits on the word "teen" but doesn't say from where: in browsing history? Throughout the drive? In unallocated space? This guys is driving me bonkers!
He's trying to make some weird case for the defense but as someone who has been involved with several forensic investigations, I'm not buying it. Try not to worry...Juan's got this
