Get them out criminal vermin
Closed down an airport due to their actions costing thousands of people time, money and stress and they demand an easy sentence.
'rights campaigner' doesn't give a right to special treatment. By all means protest within the law but when they broke the law they should pay the price. The judge should make an example and give them the maximum sentence or anyone could claim special treatment for any crime
Lock them up, set an example. People need to know this is unacceptable!
I have no problem with the reason for their actions, but you have to avoid establishing a precedence that legitimatizes this as a form of protest against an unrelated issue.
