Nigerian Letter Scam

The 'Nigerian Letter Scam' is a scam that people from Nigeria have been pulling for some time now. They send you a letter claiming to be a government official from Nigeria. They then tell you that they are planning to 'Illegally Smuggle' the money out of Nigeria and ask you for information; Bank account numbers, Credit card numbers, social security, etc. Then they ask you to send them money in different amounts or payments and usually promise that you will get bigger returns once the money is spirited. The truth is that once you send that money away, it doesn't exist. To add to all this, they sometimes lure people to Nigeria and imprison them. If the Nigerian government finds out about the victims of these scams, they do not take it very lightly. I guess they don't like the fact that you were even conspiring to 'Illegally' smuggle money out of their country. What do you think our government should do to these people if they catch any of them? Who do you think should be held responsible? Please answer these questions and more in the comments section.
