Example, with all the surveliance and snooping of phone calls they can't tell or intercept when jacks dad is on the phone WHILE IN CTU? Another thing that bugged me is that they basically gave him free reign with no guard, with how secretive the operation is supposedly i can't see him being allowed in, let alone allowed in with no escort or without stripping him of communication devices. Heck i cant even walk in to my local govt. office here without surrendering my phone because it has a camera on it.
Because he have no reason to snoop on Jack's dad. They think he's a "good" guy.
