It's funny that so many people are becoming increasingly paranoid regarding personal privacy, especially when it comes to electronics and the internet (ie. NSA shenanigans). Yet, in this case, it apparently defies all reason that Tom wouldn't want to turn over his PERSONAL mobile device.
Why the **** would Tom agree to give his employer access to his phone? I wouldn't, and my employee isn't even a three ring circus that leaks content to the public.
Moreover, the assumption is that there are texts on Tom's phone that implicate him. What is that based on? They had the ball boy's phone and had access to those conversations. Are they assuming that there were other convos that involved Brady but that they were deleted? Why would they only delete the ones with Tom and not with each other? Furthermore, why the **** wouldn't Tom just delete the texts before showing up for that interview? There's absolutely no reason to believe a thorough review of his phone (short of obtaining phone records from the provider) would generate any new evidence. These clowns are just so desperate to establish guilt that ANY sort of resistance automatically equates to guilt.
