The premise that Occupiers can make a difference is bearing fruit. An Occupier was denied a flight home because there were posters in his luggage and the possibility he could pass out literature on the flight and create a disruption.
You can not arrest an idea. But you certainly can restrict those with ideas from traveling.
John Charles Culatto, 34, claimed he was approached by police at Bristol International Airport who told him they had seen him "acting suspiciously" on the airport's CCTV system when he stopped to talk to fellow travellers.
He said he went to airport security an hour before his flight was due to depart, where staff found posters in his bag linked to the anarchist group Crimethinc and refused to allow him through until they had contacted the airline. He claimed he overheard security staff who were examining his luggage using the word "terrorism".
When he finally got to the boarding gate, he claimed he was prevented from boarding by staff. Mr Culatto said: "[I was told] that because of the very remote possibility I could distribute leaflets on the plane and upset people, the captain had decided not to take me aboard."
