• Research the tools that allow internet users to conceal their identity from their ISP and others. These tools are referred to as anonymizers. Are there legitimate uses for anonymizers such as search engines that do not record the user's search request, or browsers that conceal one's IP address?
• Choose one of these tools in particular and describe in detail how it is used and how it has affected law enforcement. Consider its effect not only on the detection of criminal behavior but also the collection of evidence once an investigation has begun.
