It took them more than a year to find unencrypted images on a hard drive?

If you're investigating someone for tax evasion, the "my pictures" folder is probably not the first thing you check.

If you're investigating someone for tax evasion, the "my pictures" folder is probably not the first thing you check.

It might not be the first thing I'd check but products such as Invisible Secrets have been out long enough to enable non technical people to store information in hard to find places. You can be sure the CIA/FBI knows about this kind of stuff.
