Everything prior to the last three paragraphs of my post was a joke, and so explicitly stated.
Packs of wild unsupervised dogs? And you thought I was serious?
But your comments about dogs and their utility is pretty ignorant. It is true, dogs get tired and bored. They can work only about 4 hours a day before they get bored. But they do work for free, and the handlers don't make that much.
And no, they don't let the dogs go a day without finding something. They ALWAYS plant something as a setup and let the dog find it so he or she thinks they have done their job and get tons of praise.
To avoid the "hump factor", I presume that the dogs both male and female would be fixed, as all law enforcement dogs are.
The comment about the SF situation was also inapporpriate. 99.999% of domesticated dogs would not do something like that. Those dogs were genetically bred and trained killers. The labrador retrievers and German shepards used in explosive or narcotic detection and other law enforcement are highly intelligent creatures with abilities we can't even comprehend.
One of these breeds' sense of smell is something like 60 times as strong as a human's. That sensory aspect of their brain is far more developed than any human or machine. Who is finding the bodies at the WTC?
I would rather have a K-9 unit or two at every checkpoint sniffing everyone down than some pimple-faced 19 year old with an automatic weapon telling jokes to his buddy.
If you are going to make accusations about an alleged violent or uncontrollable nature these wonderfully useful, unselfish, and intelligent creatures, back it up. Sure, my German Shepard would unleash all holy hell on anyone who attacked my wife or any other member of our family, but if I were there, I would too (although probably with a greater sense of self preservation than the dog), just as you would if someone attacked your family. She also obeys every command I give her as if she were a West Point cadet. Domesticated Dogs are not killing machines. In fact, there has never been a report of a WILD WOLF killing a human.
Show me an example- ONE - of a trained detection dog or K-9 police dog in America attacking anyone its handler did not intend for the dog to subdue.
The very fact that you are so terrified of the dog idea lends credence to to the deterrent affect. It's one thing to fear being shot - it's another thing entirely to fear be taken down by a pissed-off police dog. K-9 dogs subdue criminals with guns every day because they are often more terrified of the dog than of the officer's gun. Lord knows how many officer's lives these dogs save every year.
Don't take my word for it. Ask a cop who works with a dog.
