OK, i did some research.I found a site full of court cases that say the dog didn't find the drugs,he was comanded by his trainer/handler to sound off.According to this,the majority of drug sniffing dogs are useless at finding drugs.The dogs are used as a means of being able to search a bag or vehicle.When they bark or react or whatever,the officer has the right to search.Noone can question the dog,so noone knows why he barked.Video tape shows the dog reacting to a command,not scent.The site is...rexcurry.net/drugdogsmainr.html...
