If Danny is an inside man then he could disappear forever or far more likely be given a trial in the UK and receive a light sentence - one which he has agreed to as part of this job. Snowdon has proved that Secret Services are being used for commercial sabotage - incase there was any doubt.
Almost the same for Mark K, at one point I was convinced MtGox was a Gov operation.
If Danny and/or Mark are working for
Secret Services they might end up dead to prevent ever talking.
Not the type of job most "normal" people would want.
