"Many time on this show I've seen LEO, after being told 'consent to search' is NOT granted, the officer states no problem, but due to your lack of cooperation, they'll call a tow truck, impound your vehicle and it WILL be searched. In essence, you are now out your vehicle, the search will happen, except it's now really going to cost you. So, Mr.Citizen, are you certain you want to refuse consent?"

I watch Live PD pretty much every weekend. I've never seen the police tow the vehicle away if a search is refused, however, I've seen many times if the search is refused they have a drug dog go around the car and if he "alerts", that seems to give them probable cause to search as they go ahead and do it right then, without a warrant.
