First and foremost the law is unconstitutional since it is in direct violation of the 4th Amendment to the Constitution

In other words, if the federal government wants the authority to wire tap all of us without prior proof of probable cause the proper and LEGAL method of doing so is via amending the constitution, a necessarily difficult process because the founders knew it should NEVER be easy to make changes to the constitution.
