'My point is that the police can't do their job without information, and almost all information given to the police is volunteered by innocent people. Far fewer crimes would be solved if everyone clammed up when the police knocked on their doors, and that'll inevitably lead to more crime.'
Right. So let's just remove the need for a warrant, and revoke the fifth amendment. You have nothing to fear if you have nothing to hide, citizen.
That isn't really fair. I took great care not to say that people should feel compelled to give information, only that we should feel obliged to provide it voluntarily under many situations. (Certainly not all situations, either -- information given in confidence should be inviolable without a warrant, for one thing.)
