In our local high school now they bring in dogs and sniff down the school parking lot for drugs, guns, I don't know what all. I watched one dog hit on a car, watched the school officials go in and bring a student out to open his car up. In front of several cops and K9 handlers, school officials, teachers, janitor, you name it, the dog carefully and professionally worked over the inside of the car eventually uncovering a well hidden and cleverly disguised.............apple. That poor kid was just shaking, scared to death asking to call his parents while the search was conducted, which he was not allowed to do until things were wrapped up. I don't know how good those dogs really are, but I am always suspect as I have personally had $5000.00 lion hounds look me in the eye and SWEAR that porcupine peering down from high in a ponderosa was an 8 foot tom. Also have watched high dollar setters lock up on meadowlarks.
One of my buddies lives close to the school and has kids attending there. Their friends park cars at his house and walk the 300 yards or so to the school so that things are handy for a quick after school hunt, and so they aren't subjected to this kind of lunacy. Sign of the times, I suppose, but I know more than a few parents who would not take the idea that their kid was not allowed to call them laying down.
