§ 191 Restraint which is permissible.

When someone is arrested and held in custody, officers can only use the amount of restraint that is actually needed. This means things like handcuffs or other physical restraints should match what the situation calls for, not go beyond it.

The point of this rule is to protect people from being treated more harshly than necessary while they're being arrested or held. Officers can't use excessive force or restraint just because they have the authority to make an arrest. The restraint has to be tied to a real need, like preventing escape or protecting others, not used as punishment or for convenience.

This matters because it sets a legal limit on how officers treat someone in custody, even before that person has been convicted of anything. If restraint goes beyond what's reasonably necessary, it could raise legal questions about whether the person's rights were violated during the arrest or detention process.
