Or perhaps someone else knew the story of why SS gave it to JW. A friend, someone at the car inspection place?
LE knows about it and has investigated it and not charged JW with anything.
I am well aware that LE has investigated JW and that he has not (yet) been charged with anything AFAIK.
I think assuming he has been investigated and cleared is equally as valid an opinion as saying he has been investigated and will be charged when LE has all their ducks in a row, or even that LE has investigated and is holding him on a sealed warrant.
Since LE has not told us the results of their investigation, it is sheer speculation to say the investigation resulted in 1) JW being cleared, 2) evidence discovered that points to JW's unwitting involvement 3) JW being the mastermind behind a burglary that went bad or 4) JW being the mastermind of an evil premeditated torture murder where the coup de grâce was to be the burning alive of JW's 10 year-old rival for racing fame.
