I may be able to add a few that I've been compiling since November. I posted some of these earlier in this thread
http://www.flyertalk.com/forum/16013237-post27.html. The story links are attached.
You already have most of them but there may be a few others in that post.
One suggestion though. The site name and title may turn some folks off and create the impression that this is a fringe site. It would not be something say a regulator or legislator would be inclined to cite as a source even though the stories are valid. This is a very professional looking and it would be a shame if folks clicked away due to an initially negative impression. (No doubt that most folks here share the sentiment though.)
Perhaps TSA Incompetence (as you mention) or TSA Failures, TSA Misconduct or some other more professional sounding phrase would imply higher credibility.
Thanks for your effort and the great job building this. I'll post back with any other stories I have archived.
