For law enforcement the main thing they need is what is on your hard drive. You can use proxies and other means of hiding and you should as big brother is watching. One way not to have anything on your hard drive is to have two of them. One for when you are on sites like this or other sites and things you write that you do not want law enforcement to find on your hard drive. And one to use for business or other personal use. When your computer is off plug in the hard drive you want to use and when you are not using the one you want to keep private keep it off site, not on your property. I am not advocating that anyone use this idea to do anything that is not legal! I am only throwing out an idea to help protect your personal privacy. Your service provider will still have the information on sites you have visited but your hard drive would be safe from anyone looking at it. Please do not use this idea for KP, searching for kids to have sex with or anything like that. I am only bringing it up as a way to protect very personal and private information about your life that no one should have the right to look at. This is just an idea to use if you want to keep this part of your life a little more private, it can be a pain in the ass to do it this way though.
