So you jumped to a different conclusion from a different set of prejudices.
These are extreme times. Failure to "speculate" as to what can happen, can lead to that very thing happening, although I am powerless to stop them, others are'nt.
I applaud the LEO for recogizing a potential threat in form of suspicious activity, and further applaud the bomb dog action....even though the dog appears to have been wrong, had the dog been right, we would'nt be having this thread right now and the LEO would be cheered a "hero" for going on a "hunch".
As for my Tin Hat about Mossad, I'll say it differently. Only a fool would belive that Israel could refrain from such activity. The U.S. is capable of doing the same thing in other nations to acheive any goal the powers that be deem worthy of "covert" operations, IMHO.
