Citizens have the right to peacefully protest, but not the right to protest in a way that disregards police orders and disturbs others. Thunberg is not being prosecuted for her political beliefs, but rather her flagrant disregard for the law.
The real crime here is the continued use of fossil fuels that are killing innocent people and continuing to destroy the future of our planet. It’s no longer acceptable to be a passive bystander to this callous destruction of our environment, and Thunberg and other brave activists should be applauded for putting themselves on the line — even if it means being disruptive to law enforcement.
