Since corporations are considered people by the Supreme Court and many large banks are known to have laundered money for Al Qaeda and their associated forces, they should be dealt with like any other terrorist sympathizer. If Americans can be killed without a trial when they support terrorists, banks and bankers that supported terrorists should be treated no differently.
The United States of America should begin to dismantle the terrorist funding, money laundering, American killing, big banks and other corporations by targeted unmanned ariel vehicle strikes. Of course, collateral damage should try to be limited but sometimes one has to break some eggs to make an omelette and sometimes the only way to break that egg is to use a Predator missile.
