Individual liberty equalling counting for criminal law, not civil law nor morals in effect in a society or community. E.g. in a club in San Francisco you might be checked before entry to prove you do not possess a knife or gun. Whereas in a club on the beach near Rotterdam anything goes. In the case someone gets stabbed or shot in the club in San Francisco its unlikely they passed security. Whereas in the Rotterdam example such boundary does not exist.

That’s not quite right — they’re establishing a baseline to believe something worthy of depriving someone’s liberties over.
