I believe they call that "detained". He's cuffing you for his safety until things are sorted out.
Thus the courts have ruled. Unfortunately, it has become policy, instead of a judiciously applied judgement call.
Handcuffing a well known billionaire “for officer safety” is quite a bit different than handcuffing a carload of speeding ruffians with gang tattoos “for officer safety”.
One size is applied to all, in the sacred name of political correctness.
