So, essentially, regarding the checking of the computers, we have the following situation:
- Potentially months old data.
- Data that was possibly wiped at some point or even never recorded, which would mean that it's far harder or even impossible to retrieve as it may never have existed in the first place.
- A police force who have no target as to what they're actually looking for, because they don't know anything about any internet activity of Andrew's.
- If any data was found, it would be a complete mess potentially spanning thousands upon thousands of different students, or with the library thousands upon thousands of members of the general public.
- Seemingly individual computers were taken, which would increase the mess of data even further. The school had over 1,000 students. If we aim very low and say a few hundred computers, then say a dozen or so for the library, that is an absolutely incredible amount of data to look through, especially when we consider that Andrew could potentially have been visiting websites online at a school or library for who knows how long.
- Two libraries that (from memory) were actually closer to Andrew's home and school than Doncaster library, which were not searched according to the article above.
