Under this law, if the President determines that a foreign person or organization has knowingly committed acts of piracy at sea, the U.S. government would block that person's property or assets located in the U.S. and deny them entry into the country. Anyone who tries to get around these penalties — for example, by helping move blocked money or property, or by conspiring with a sanctioned pirate — could themselves face fines or criminal charges. In short, it gives the President a tool to financially and legally punish people involved in sea piracy, along with anyone who helps them dodge those punishments.
