As far as civil liberties go you can find many examples if you look at law enforcement search and seizures. One that stands out was a couple of guys who were professional gamblers driving to Vegas. Stopped for a minor driving infraction, the cops called in a canine unit who got a hit on their trunk. Well they had thousands of dollars, which makes sense. Two pistols, which makes sense. But the cops grabbed their shit anyway and now they're battling it out in court. Stupid.
