Sure. They should also jail him until he IDs himself, or he dies.
In the context of a legal ruling, "a person may do X" means "a person may do X without being legally punished."
Nonsense. Particular conditions were attached to the waiving of sanctions for refusal to ID.
Irrelevant; it remains true that in the context of a legal ruling, "a person who meets condition Y may do X" means "a person who meets condition Y may do X without being legally punished."
Trivial. It does not apply to condition z.
