This goes back to the term "pay to play" which also means "If you take something, give something back". The "damming" evidence you are referring to is an affidavit, which are excerpts from a larger FBI transcript of just one conversation. Affidavits by definition are not evidence, they are press releases designed to bolster support for an arrest warrant without having to provide any information to the contrary. The FBI has the luxury of picking and choosing what they want you to hear, and I can guarantee that you have not read the entire transcript since it pertains to an ongoing investigation. It is the job of the FBI to prosecute as many people as possible for any reason imaginable, if they don't then they're not doing their job.
