  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.
