The FBI shuts down a site with hundred of thousands of user because of 36(!) infringing files This I've never understood. I thought the US upheld the principal of due process. Is it really possible to shut down a person's business without a civil or criminal conviction? What I find odd is that I'm not familiar with any cases outside of the Internet space where a business was shutdown during the process of an investigation. I'm sure there are examples somewhere, but it still seems wrong that the executive branch has the power to shut down a business without judicial review.
