Use a little imagination. They can can accuse LENR advocates as aiding terrorists. They can plant child porn on their computers. They can make an example of any one of them by murdering one of them and pretending it was a suicide - or just a "random" crime that never gets solved.
And you think Europe is free and democratic? Do some research on "Gladio" - watch the BBC documentary on it and learn how innocent men, women and children were killed in false flag operations and blamed on radical leftists. If Europe - or the US - really had equal protection under law, then I would expect that at least ONE big/central banker would be sent to prison. Since that hasn't happened, who do you think is in charge?
