Good question. I addressed this question at the link
below, I won't reprint the whole article here, but this
is something to consider:

http://blog.zonelabs.com/blog/2006/06/forensics_looki.html

While it's good they got the *hardware* back, recovering the laptop it
self doesn't mean the data wasn't stolen.

Speaking to this concern, another report stated this:

    The FBI, in a statement from its Baltimore field office, said:
    A preliminary review of the equipment by computer forensic teams d
etermined that the database remains intact and has not been accessed s
ince it was stolen. A thorough forensic examination is underway, and t
he results will be shared as soon as possible. The investigation is on
going.

As a former Computer Forensic Specialist, I wanted to explain what's p
robably going on with this laptop now that the FBI has the system and
is forensically examining it. This explanation assumes the data was pr
esent on the hard drive (not a CD-Rom or other storage medium).

...

Worst case scenario:
The laptop thieves really know what they are doing. They remove the
hard drive from the laptop, and mount it read-only (no modifications to
the file system) on another computer, access the sensitive data and
re-insert the hard drive into the stolen laptop. This is the same process
the forensic examiner would use to prevent the examination from modifying
the data contained on the laptop -- and this is why I mentioned
what the FBI might look for during the physical examination -- marks on
the screws or finger prints on the internal hard drive casing (which gloves
would obviously prevent).
