But he goes on to say:

"Looking at this from the other point of view, with the ever-increasing
data density on disk platters and a corresponding reduction in feature
size and use of exotic techniques to record data on the medium, it's
unlikely that anything can be recovered from any recent drive except
perhaps a single level via basic error-cancelling techniques." 

So even those few passes of random data are overkill.

The police just take disk images.
