Is It Necessary to Pass a Law Giving Parent's Access to Children's Text Messages?

Is it really necessary Arizona to have a proposed law to give parent's access to their own child's text message or should they have that right if they are footing the bill?  Apparently, parents are currently required to obtain a court order to view their child's text messages in Arizona and other states.  I think that the courts are going overboard when it comes to the rights of children.  Parents should have the right to protect their children in the cyber world.  With the increase of cyberbullying, social networking and predators using the cyber world, I see this as a no brainer.  Text messages and postings seem to hold clues as to what your child is thinking or doing.  Often times the news will quote text messages or facebook postings from school shooters or teen suicide victims that clearly indicate their intentions long before the event occurs.  If parents have the ability to keep a closer eye on what their children are doing in cyberspace, some of these tragedies may be avoided.
