No border-based need to expand wiretapping

Here's a non-solution searching for a problem: Currently wiretapping in Texas is limited to prosecuting drug trafficking and murder, so Texas Governor Rick Perry announced he wants to expand eavesdropping authority to combat border violence. But that makes no sense - aren't drug running and murder exactly the crimes we're trying to stop on the border? How much more authority could they possibly need to use wiretaps to combat smuggling rings? The whole thing seems like an odd non-sequitur - another idea promoted for show that doesn't make anyone safer.
