It's a sign of the times, but, you may want to know your digital rights before the suits knock at your door. The Electronic Frontier Foundation website provides a Q&A section with helpful tips. The best tips are the same whenever dealing with law enforcement: 1) don't consent to a search 2) don't answer questions and 3) ask for a lawyer. A printable pdf file of the Q&A is available here. You can take an EFF quiz here to check your digital rights IQ!
