Shockingly enough, I am against police brutality. http://www.flyertalk.com/forum/wink.gif

But, frankly, if a dog smells and explosive on someone and goes nuts barking, I think that's a hell of a lot better reaction than some x-ray jockey missing it altogether.

I don't think innocent citizens would be barked at, slobbered on, jumped on, etc. If they are looking for explosives, etc., and thye find someone with traces of explosives, having a dog bark at them is not something I would worry too much about. If you are worried about a dog biting someone, you absolutely can train a Shepard not to bite or jump- just to bark, and you could also just use a less threatening dog like a Lab or Golden retriever.

Unless an innocent citizen is carrying explosives, I don't think we have to worry much about them being barked at.

Frankly, having guys with big guns scares me, an innocent civilian.
