I would urge every one on FR to consider doing the ride along with police. I suspect there is more to this case than just a "nervous" driver. (Dare I say profile?)
It has long been the case law to allow for the calling of a police dog. That part is not new. The issue is the sniff outside the car.
Also keep in mind this is the same court that said police can not use technology to "see" into houses without first obtaining a warrent. (just b/c tech advances does not mean police can bypass laws)
Anyways, do the ride along it will confirm both bad and good.
