Vague laws set vague limits on people's freedom, which makes it impossible for them to know for certain whether their actions are legal. █████ █████ █████ ████ ██████ ██████ ████ ███████
If laws are vague, people cannot feel secure. This is because it’s impossible for them to know for certain whether their actions are legal.
The support is about lack of knowledge, but the conclusion concerns lack of security. We need to connect the two. Consequently, to guarantee the conclusion, the author must assume that, if people don’t know whether their actions are legal, they can’t feel secure. (Contrapositive: if people feel secure, they must know if their actions are legal.)
