... as crazy as it sounds, that felony becoming public might not be as unrelated as it might seem on the surface. Doesn't the SEC have some say in Prosper's future? And aren't felonies something that can disqualify you from certain positions under SEC jurisdiction?
You guys are excercising fantasy. An arrest isn't a felony. In the United States we have this little rule called "innocent until proven guilty". So, no.
This is a common misperception, but "innocent until proven guilty" only applies in criminal trials. In other contexts, mere arrests and/or charges filed (without a conviction) can have serious repurcussions. Someone can be held in jail for an extended period of time pending trial, for example, despite being "innocent until proven guilty" for purposes of the trial (for example, OJ spent what, about a year in jail after his slow speed chase in the bronco before being acquitted in his criminal trial). And although OJ's slow speed chase may have indicated an attempt to flee, many others are held in jail pending trial without any such facts, whether because they can't make bail or because no bail is allowed.
Besides pretrial detention, there are other negative ramifications that can flow before a conviction. For example, an attorney arrrested for certain types of crimes will be summarily suspended from the practice of law pending disposition of the criminal charges. That means he/she can no longer support him/herself by practicing his/her profession. I believe that an arrest of a teacher on certain types of charges will also lead to being removed from the classroom, and even if acquitted of the charges (or if charges are never filed), can still be prevented from returning to the classroom. And, of course, arrests are public records, so publicity of an arrest can cause all sorts of reputational harm even absent charges or conviction.
However, in this particular case, I agree that attributing JW's sudden departure to Bama's scoop is pretty fanciful. I can't imagine that the SEC (or anyone else) would care very much about a smoke bomb at a sorority event 20 years ago when JW was in college, regardless of whether he was ever charged and/or convicted of anything.
