citing individual cases is meaningless...just like quoting you smoking since you ere 15.....doesn't prove smoking is not damaging to health...or perhaps you think it does
The point, davel, is that statistics just give us probabilities. The statistics on smoking and health may tell us that x number of smokers will suffer from y number of smoking-related diseases. They can't tell us which individuals will suffer from these diseases. They can only provide the odds of an individual suffering.
By the same token, statistics relating to cadaver dogs and handlers can only tell us the odds of false alerts happening. They can't tell us anything about individual dogs and their handlers.
Science has been hugely successful because it mostly works with inanimate objects, not people.Human beings can't be studied like rocks or trees, because they think and react to the circumstances they find themselves in. Testing will affect the dog's handlers. Some may not find the testing stressful, but others will; just like exam nerves. Dogs will pick up their handler's mood, and if the handler is stressed the dog will be stressed too. Testing will not replicate the success rate of the handlers and dogs when they are working in the normal way, it will add pressure which will affect the results.
