Partially because that kind of information can't be used in court. The fact is that text messages are extremely insecure. If the US govt is willing to spend hundreds of billions on spy satellites and submarines, isn't it reasonable to assume that they would spend a couple million to gather all text messages? They're not supposed to spy on US citizens, but there are enough loopholes to allow it. Just because the NSA has huge amounts of data doesn't mean that the FBI has unlimited access to that data. The NSA historically doesn't share information with other agencies. Many claim that the NSA knew the details of 9/11 but were not allowed to share this information. Then the Patriot act and "secret patriot act" came along and more information is allowed to be shared between agencies, but not unlimited information, as far as the public knows.
