The RIGHT Way to Handle a Police Stop

I've seen these two videos a long time ago and they are GREAT advice. It's actually scary the kind of stuff the cop says he has done and other cops will do to you during questioning. In the UK, where I'm originally from, the police are not allowed to lie or ask you to do anything outside of your rights and so it is total wake up call for anyone who is not used to the way the police work here in the US. This video is also useful, [this video] However, a friend who I talked to about this did make a counter perspective... that sometimes it is worth talking to the cops in the right circumstances. For example, if you are pulled over cos you just ran a stop sign and you have nothing illegal on you/in the car/etc then it is better just to talk to the cop and get the ticket dealt with. If you start playing the 'not going to say anything' and 'no you can't look in the car' then you are opening yourself up for a long painful experience and potentially arrest if they decide to fuck back with you and they can pin some suspicion for something on you (eg you are driving through an area that happens to be associated with drug sale, you have a LeatherMan tool you and the cop can say the knife was being carried for other intent, etc) Cops are naturally authoritarian and can choose to make your life hell if they think you are trying to be superior or above them.
