I dunno, but when I think of bomb-dogs, cadaver-dogs or drug-dogs, I tend to think that if certain substances are within a certain vicinity of their smelling ability, that they'll react in the manner they either know or have been trained to do. And dogs can smell things at incredible distances. Particularly if they've been trained to do so, and know what they're smelling for. When the dogs are out there with their handlers, they know they're working. I don't know the technical footage of their sniffers though, but it is impressive, to say the very least when you compare it to our standard of smelling.
Having said that, and having read the eyewitness report that there were bomb-dogs at both the start and finish, I am naturally curious about how this particular event unfolded in the first place. Because I imagine that a bomb-dog lead police to the bomb that they personally detonated. So why weren't the dogs alerted to the two bombs that went off? Were they out of range? Had the area not been swept in a while?
The "Press Conference" tonight was terse with information. It is not hard to tell the American public exactly what WE were doing at the time of the event, or had done or had NOT done prior to the event. They don't need a few days, weeks, months or years to come up with a story. This, "I cannot confirm or deny these allegations," type answers out of people with authority after events like this need to stop. WE SHOULD WANT TRANSPARENCY! Right? Seriously, man. Every time something like this happens, important questions are immediately blocked by some catch-all authoritative jargon, and we have to accept it. This is America. And I presume everyone that is reading this is an adult, but we should be treated like loyal American adults and given answers when asked, not unpatriotic foreign children that are denied everything they ask. When you're told, at age 21, 25, 30, 35, 40, 50, 60 and on up that you can't know something by someone in authority, how does that make you feel? Am I the only one less than happy about it?
