They have the duty to do that, only he has the right not to answer, despite not having been told so. You have to defend even terrorists' rights if you want yours to stand.
Completely agree with this. Unfortunately most people are too stupid to realize that in order to protect your constitutionals rights you must also protect the rights of people you do not like, i.e. hate spouting religious extremists, of any religion. Even the rights of killers like the Boston bombers must be protected if we want ours to be protected.
I do not know if you were simply clarifying the parent post or actually referring to the Boston bomber, but the fact of the matter is, you become a "convicted felon" when you've found guilty in the court of law.
you must also protect the rights of people you do not like. Even the rights of killers ... must be protected if we want ours to be protected.
