This morning on ABC News24 after 8am the AFP head honcho in Canberra was being interviewed and when questioned about how the demonstrators got such easy access to APH and THE ROOF he said "there were hoax phone calls made to the AFP to take personnel on duty to locations way-away from APH" -- leaving the building "easy for demonstrators to access and do what they like" .
Sounds like sophisticated crimes were committed.
