"closing the clinic would threaten the drug users’ health and lives, contravening their constitutional right to life, liberty and security of the person"

I find this statement very ridiculous. Aren't the drug users threatening their health and life already (and endangering other people's life as well)? So they make them secure and guarantee their freedom, how about the security and liberty of non-drug users around them? I guess I will never understand the idea of freedom in some parts of the world.
