I'm not sure if I'd be comfortable doing business with a guy who tells people to erase their phones after they rape someone.
I'm also wary of people who don't understand how permanent the internet is.
Below is a photo of Jon's Google+ account which shows him as both the owner of Jon Lawson Research and Consulting and the guy behind @JonLawson32 (https://plus.google.com/109527402958302672781/about). He also previously worked for the Idaho Department of Health and Welfare.
I hope that when you are considering hiring Jon as a consultant, that you also take into account his personal views of what to do if you rape someone (delete your stuff).
