Certainly an Odd Terror Plot

The Washington Post story:

President Obama said Friday that packages mailed from Yemen and intercepted in the last 24 hours contained explosive material and represented a “credible terrorist threat.”

The packages, mailed via UPS and FedEx, were addressed to two places of Jewish worship in Chicago, the president said…

So, the plot goes like this – Terrorists in Yemen obtain the addresses of two synagogues in Chicago; they make up bombs and drop them in the mail to do….what? Why would you do something like this? Its not like crossing the US border is all that tricky an enterprise…pay $10,000 to the drug cartels and you’re across the border. And now with toner cartridges dressed up as bombs, but with whatever bombs you want, which you can just drive to Chicago and set off. These packages were sent by means most likely to be detected from a place we’ve got our eyes on pretty intensely.

Sorry, but this just isn’t making a lot of sense to me. I’ve heard that some figure this was a dry run. What for? Why risk the exposure of your plot and your network in a dry run. Good we caught them but its almost a matter of how could we not have caught them?

I’ll be watching developments on this – it is just very, very strange.
