Really? If you were an officer, you`d have no use for the Constitution?
He didn't say that. Nor did he say that officers would have no use for the Constitution. If you - as a theoretical police officer - have to wear an uncomfortable ballistic vest because you never know when some armed criminal is going to shoot you, that might lead to a couple of reasons you might prefer an "unarmed citiizenry." Says nothing about devotion - or not - to the Constitution and the Second Amendment thereto.
