I believe that I have figured out the method the PSP is using to remove offenders. I have been watching the list for a few weeks and taking detailed notes. I believe what they are doing is, focusing on and removing the tier 1 and 2 offenders with warrants. but it seems that they are leaving the tier 3s on. And they are also removing people as their registration date comes around. I subscribed to the notifications in my area and what I have noticed is that when I click on the name in the email, its now showing “not found” for anyone who’s convictions was before 2012. So I am getting the email when they check in and they are on the list but, then the PSP is removing them within a few days and its then being showed as “not found”, even tier 3s.
