Just wondering

Reuters reports today that

[t]he Madrid train bombers had detailed plans of New York's Grand Central Station, indicating they also planned to attack there, a Spanish newspaper reported Wednesday.

Hand-made drawings and other "highly specialized technical information" about the station were found on a computer disk seized from the home of one of the suspects, El Mundo reported, citing sources close to the investigation.

Now, I'm always suspicious of this kind of extrapolation, turning possession of information into a conscious intent to use it for a particular purpose.

But to the extent that the judgment that there was some kind of plot against Grand Central Station is accurate, doesn't that sort of blow a big hole in the tired claim that the Madrid attacks were undertaken in order to affect the Spanish elections?
