Stop with the dogs already! Sink, you're too wise for that. Even I can tell that the dogs are purely a prop - None!
How many times in just the last week have we heard that dogs indicated the prosence of explosives and then nothing was found? At least twice. There was the case on Wednesday where the dog indicated there were explosives in a laptop and inside a box of a person detained on a flight. That was BS. Cops blow up the box and it had nothing in it. Fortunatly for the poor guy detained, he was able to convince the cops to not blow up his laptop just on the dogs say-so. They took it apart and put it back together - no explosives.
The dogs are a sham - just an excuse to get a search warrant.
Dogs find as much as they miss. So, they're more than just a prop.
