I believe that the state and federal government should be able to monitor the internet because it is a public place where people should have nothing to hide, the constitution has no provisions protecting internet privacy, and because monitoring the web can prevent crimes before they happen.
When you post something on the internet, it is understood that anyone can see it and use it for or against you. People know that whatever they post could be seen by potential bosses, friends, and parents. Therefore, no one should be posting things that they wouldn't want their grandma to see, let alone things that could get the FBI sent after them. Anyone who is proficient at hacking can monitor the internet, so why shouldn't the government be able to? People who have nothing to hide should not worry about being monitored by the government since they are choosing to post things for the public to see.

All of these protections are made to keep the government from disturbing people's personal lives. However, things posted on the internet are not personal, they are public.
