"Smell" as probable cause needs to disappear.

As an extension of this, the existence of drug dogs is extremely irritating to me. It's been seen more than a few times that they're commonly trained to react to a cue rather than genuinely detecting illegal substance. Dogs aren't conscious, and they don't have a sense of morality. I have a huge problem with them being used by police and that their 'opinion', if you want to call it that, is respected in a court of law. A dog cannot testify in court. A dog doesn't realize it is lying. It's insulting to the legal system.
