Seizing evidence under a contrived and false pretense is wrong, regardless of how heinous the crime might be. If you accept nonsensical porn-sniffing dogs now, what will it be down the road that might be directed at you, being the deplorable that you are?
What is nonsensical about using a police dog to search? Pretty standard police procedure. What would you prefer? A Swedish bikini search team?
Or are you suggesting internet crimes like child abuse should not be investigated? You make no sense. As usual.
I think RC is believing that the perp is somehow tricked by being told that dogs can actually smell content on a drive.
This is no different from drug-sniffing dogs. Search warrant is presumed.
