“After answering the stop related questions ask if your are being arrested. When they say no, state that you would like to leave as you have pressing business elsewhere.
The police may not detain you without cause. The longer you are in contact with the police the greater chance that they can manufacture a reason to arrest you.”
The police can say they are conducting an investigation and detain you while they proceed.
Correct me if I’m wrong, (Lord knows I was almost wrong once way back in ‘92), but I’ve heard the police can ask if you’d wait while they get K9 out there to “sniff’ up your vehicle.
Failure to allow this results in the cops then assuming you’re actually trying to hide something which allows the “investigation” to then proceed (warrantless entry to the vehicle).
I even watched a thingy online(?) or was it tv(?) where the “K9 handlers” can issue commands to the dog resulting in the dog “alerting” on something that isn’t there allowing them to search..
IOW, if a bad cop wants into your vehicle, they’ll get in..
