Please don’t take away the stupid criminals. You could underpopulate the jails. No one in their right mind would want to try to convince an officer that he had nothing to hide. Thats like keeping your driver’s license in your Bible and leaving it on the dashboard so the officer will know that you are a Christian speeder. Cops aren’t going to ask if they don’t suspect something. If they get permission, then it isn’t a search and evidence won’t be suppressed for lack of probable cause. The argument becomes was the consent voluntary? That is easier for a prosecutor to argue, particularly because “people who don’t have anything to hide always comply”.
If you believe this then I have a bridge, some prime real estate in the everglades and a perpetual motion machine you might be interested in investing in.
Being THAT naive will get you into trouble one day.
