I just found out my mother's pet crip was paroled. What should I do?

Background Info:

My father was very controlling. He wouldn't let my mother go places. If she did get to go somewhere, he would freak out if she wasn't home by the exact time she said she would be. When he died, my mother went ballistic. She now had free reign and sought to control everyone else.

She also went a bit nuts. While working as a correctional officer at the local prison, she had become friends with a crip from LA. After she retired, she kept in contact with him. When he had some troubles, she helped him break parole by letting him move in with us. I had no say in the matter and it freaked me out. He had a huge rap sheet and despite my mother's assurances that this gangster had merely been in the wrong place at the wrong time (many, many times), I was afraid of him.

Then she helped him move into an apartment in Modesto, which was totally against the terms of his parole. This convict was her pet project. She warned me against telling anyone in the family, making me promise to keep my mouth shut, yet wanted to involve this man in my life.

A lot of weird-ass stuff happened. The crip went down to LA and got himself shot up by rival gangsters. They hit him seven times, but he still didn't die. My crazy mother drove down to see him every week while he was on the mend. It's an 8 to 9 hour drive and she went every week. My brother, the correctional officer, still doesn't know a thing about it.

Finally, he got picked up on a parole violation and went back to prison. Recently, I used the Megan's Law pages to keep tabs on him. He was listed as incarcerated, but today while telling the story in another thread I opened up the Megan's Law pages again and discovered that he has been paroled.

Sweet Jesus...should I tell my brother and stop this shit from happening again???? My brother is violent and cruel, so I'm a bit worried about his reaction. Still, I really don't think this is a good secret to keep.
