Not at all. It translates to: any person, guilty or innocent, does not have a right to privacy if the state has probable cause to believe that he has done something illegal. My point was that the dog sniff itself was not an invasion of privacy. The search of the trunk was an invasion of privacy, but the cops were justified because the dog alerted the cops to the marijuana... and the dog only alerted the cops because the marijuana was actually present.
Now... if the cops had pulled over the guy for a traffic violation and searched his trunk without the dog sniff, Caballes' rights would have been violated... because even people who do bad things have rights. But the cops had probable cause.... the dog barked.
Rulings like this give the police the opportunity to put someone through Hell on a hunch.
No. Not at all. The opinion specifically noted that the sniff itself didn't inconvenience Caballes in any way... and that if it had put him through any type of hell (even just the inconvenience of waiting an extra few minutes while the drug dog arrived) then the sniff would have been unconstitutional.
So long as your confession is the only thing beaten out of you, as opposed to your grocery list, any interrogation is a-ok. The criminal does have the right to privacy, even when that privacy may end up concealing his criminal activities.
Again, no. The fourth amendment protects a person's effects except when the state has probable cause to search or seize them. The fifth amendment protects a person from being compelled to incriminate himself without qualification... That is to say, there is sometimes justification for invading privacy but there is never justification for compelling self-incrimination.
