I doubt the money being moved out would have been in any danger had it stayed put. It could mean that we're putting a crimp into money sources overseas and this is a reserve source already in this country. Of course a mistake on anybody's part could always let the cops confiscate a discovered stash.
I do think we are now in a waiting mode for an attack.
After they wire the money back they will probably first exchange it for gold and then attack.
If we could identify terrorists stashing money in our banks and financial institutions, we'd have a windfall of cold hard cash to help fund our war on terror and buy equipment for our troops in harms way.
Not long ago Rush was targeted due to bank withdrawals under $10,000. If we can monitor our own citizens for large withdrawals, why not the same scrutiny on foreign nationals who either deposit or withdraw large sums of money? After the initial deposit is made, a cursory investigation of foreign nationals should be required and funds frozen immediately if terrorist links are found.
