Spoiler...Didn't Peter actually blow the case?
Peter went to the club with the boombox and recorded all of the things that Widow said that would implicate himself in illegal doings. Since Peter went in on his own without any court order or anything like that, wouldn't that get Widow's case thrown out? Wouldn't that also put Peter, his family, and Charlene in more danger since Widow would probably be seeking revenge?
