  1. What a comprehensive list of resources. Thank you! I was a licensed PI several years ago and am trying to refresh my skills because I have an interview for an investigator with the public defenders office. Technology changes so rapidly and many of these resources were not available when I last worked as a PI. I could spend countless hours on your website looking at all the interesting links you shared.

  2. Thank you for the exhaustive list of private investigator tools! I’ll let you know if I can find anything that would be useful to add to your list here.
