This is the number one flaw with the "rule of law" and State authority structure. The enforcement of the law always comes down to how the ruling body of authority, the State and its representatives, interpret the laws. It is why they are intentionally written to be vague, to allow a court wiggle room in how to apply the letter of a law to a unique situation, and many in fact contradict each other if argued a certain way.

If the system becomes corrupted, which it often is due to how top-down power attracts people who seek control over others, those vagaries can be used as weapons against those who oppose their power and to systematically exploit marginalized people.
