Passage Summary: If laws aren't clear, you can't be sure if you're breaking them, and if you can't be sure of that, you can't feel safe.

Conclusion: People living under vague laws are unable to feel secure.

Reasoning: Vague laws create uncertainty regarding the legality of one's actions because they set unclear boundaries on personal freedom.

Analysis: This argument contains a classic 'Gap' between the premise and the conclusion. The premise establishes that vague laws lead to 'uncertainty about legality,' while the conclusion claims this leads to a 'lack of security.' To make this conclusion follow logically, we need a Sufficient Assumption that connects these two distinct concepts. Look for a conditional statement that says: 'If it is impossible to know for certain whether one's actions are legal, then one cannot feel secure.' This link would guarantee the truth of the conclusion based on the provided facts.
