Short answer...he's the Speedway (Indiana) Bomber. Convicted to a 50 year sentence, for the bombings and drug dealing. He was also found liable in the civil case for maiming Carl Delong and his wife with one of his bombs, and has never paid a dime in restitution.
The long answer is so convoluted Kafka couldn't write it, even though it's all true. Lawfare is the term the more lawyerly types are using. Using the courts in nuisance suits to shut down free speech and to hide his past...This has taken over 3 years to get to this point(that I'm aware of, it maybe a lot longer...), and there is so much, and so many folks involved it will probably be more than another 3 years in unraveling.
Socrates can tell you about himself and the suit Kimberlin brought against him for truthfully stating on his blog what Brett Kimberlin has been doing since being paroled & then having his parole revoked.
Aaron Worthing can tell you how Kimberlin tried to frame him for assault, and in the process cost both Aaron and his wife their jobs.
Stacy McCain can tell you all about Kimberlin's links to the worst of the progressive left, and how they try to shut down folks that disagree with them. Stacy and family have now had to move to an undisclosed location because of threats to their safety. (take the time to read all of his posts on this. Yeah, you are going to feel like you going down Alice's rabbit hole, but stay with it. It is important no matter what side of the political spectrum you are on if you value honesty)
This is one of the posts on Kimberlin I read over at Patterico's Pontifications in Nov of 2011, though not the first, nor the last. At that point I think even Patterico felt Kimberlin was just a nasty joke, but no longer,as you will see! Patterico has been harassed at his job (he's an assisant DA for L.A. county) His boss, the DA has been harassed, The receptionists in his office have been harassed! His wife has been harassed at her job. All by either Brett Kimberlin, or folks working on his behalf. Be sure and read his post today , it will be important!
This IS an important story. It doesn't matter if you are a liberal or a conservative, or don't even want to be bothered by politics. I've followed it off and on for a long time now, and even I just keep thinking Oh. My. Dog! everytime I read another "chapter" in this on-going crazy saga. The things and people involved just seem to keep growing and interconnecting in bysantine ways most people can not even conceive of.
It affects all of us. There are evil people in our midst, and I'm not exaggerating. They will use and/ or destroy anyone that gets in their way. YOU need to know about these people, so read the links. Think about what these folks have done and are willing to do. It is important to you whether you know it or not.
And then stand up for what is right.
