Should cellphone companies be allowed to wiretap?

The President wants to let cellphone companies get away with illegally wiretapping people's cellphones, to "protect" us from Terrorists. He argues that we will be stopping another 9/11 from happening, and that spying on people will save lives and create a better sense of security. Others say that no one will know it's even happening, and that there wouldn't be enough evidence to convict the companies doing it. I believe that as Americans, we should have the right to privacy, because it seems unfair that companies should have the right to invade your privacy. As for "stopping another 9/11", wiretapping may help spot terrorists, however I don't really think that spying on people creates a strong sense of security. Should we really trust our president on security, after all, he read the book My Pet Goat instead of the 9/11 warnings, and blamed the whole attack on Iraq, when they weren't involved at all? Post-9/11 fear has been making stupid people seem smart, as well as stupid ideas of "protection." Do we really need our phones listened to, and will it really protect people in America? There are good sides to this; it might protect people from some kinds of danger, but not terrorists. Wiretapping phones might seem like a good idea, but it is in fact illegal. It's not just against the law, it's an invasion of privacy. We should not just give companies access to personal information; companies could abuse their power and take advantage of their wiretapping abilities, to the point where it's not even about protecting America anymore. Should we keep our rights, or give them up to a failure president?
