Here's just one example of what can happen when you have a right wing Supreme Court which is willing to disregard civil liberties. Considering that a tremendous percentage of cars can be stopped for speeding and other traffic violations whenever desired, this gives the police considerable latitude to conduct searches without any evidence of a crime having been committed.
Justices Uphold Use of Drug-Sniffing Dogs in Traffic Stops
By LINDA GREENHOUSEWASHINGTON, Jan. 24 - The Supreme Court ruled on Monday that in making a routine traffic stop, the police can permit a trained dog to sniff the car for drugs without the need for any particular reason to suspect the driver of a narcotics violation.
The 6-to-2 decision set aside a ruling by the Illinois Supreme Court, which held in 2003 that a state trooper who had stopped a man for speeding had broadened the scope of the encounter beyond constitutional limits by having the dog sniff the car. The dog alerted the police to the trunk, which contained $250,000 worth of marijuana. The addition of the dog impermissibly turned a traffic stop into a drug investigation, the Illinois court said.
In the majority opinion on Monday, Justice John Paul Stevens said the dog's sniff did not amount to an unconstitutional search because it did not prolong the 10-minute traffic stop and did not violate any "legitimate interest in privacy" a driver could have in carrying contraband.
