They are simply doing the same as Paul did when he appealed to Rome the equivalent of the UN of his day biblically. To help to do the preaching work and be recognised so people can be practising Jehovah's witnesses freely.
We have absolutely no political aspirations like mormons or catholics and to the point of not voting or going into wars. We only ask that we can preach the bible God's message and our people can be witnesses in every country and will deal with Authorities as Paul himself did to this end.
If the witnesses are guilty here then Paul was also guilty for appealing to Rome.
The biblical precedent is there. We are told to submit and deal with authorities till Jesus's return but not see them as the answer which only comes from Jehovah through his son Jesus.
