Drop the extradition request and request the UK release Julian immediately. Then he can flee to someplace safe -- wherever that is these days. I doubt his home country (Australia) is safe.

A pardon for crimes he didn't commit shouldn't be necessary, but it won't hurt. However, a pardon and nothing else won't work unless the case against him is dropped. Even that isn't a certainty -- just look at the Flynn case where the corrupt and evil Judge wanted to continue anyway.

I also want to see read the grand jury documentation - bet it was all fabricated BS.
