You've made an excellent point, Kirby. According to the US Constitution, a warrant is needed to search your property. If authorities go in without persmission and collect evidence, all that evidence will become null and void should a trial arise. Classically, this is applied to an example such as suspicion of growing marijuana (sp?) plants in your home. I really have no idea how this applies to the Internet and computers. Will anyone who really knows about this stuff comment, please?
P.S. Here are some more enlightening articles.
