As far as some of the questions about FedEx locations and timing; If you do a search of locations around Miller Park, it clearly tells you the last time of express pickup on Saturdays, the latest I can see is 5PM, nobody has ground pickups on Saturday, and no pickups of any kind on Sunday. So that part of the argument from the collection standpoint would be legit, there was simply nowhere he could have dropped it on Saturday that would have begun actually transporting it out of Milwaukee until Monday. (But, dropping it off regardless has it's own benefits, as Braun described in his press conference.) At which point he made a judgement call, or was possibly instructed by his employer, to take the samples with him. According to the procedures that's probably still in-bounds (though for as explicitly as the procedure is spelled out, it lays out nothing about what to do in these cases, which I assume will be amended soon), but the question then becomes what happens from that point until Monday afternoon. There have been varying reports of how he stored the samples; in the refrigerator, in a tupperware container on his desk, and in a cooler in his basement. The right answer to that I assume could have vastly different effects on the samples over that period of time. Also, did he keep reports/proof of the safety of the samples? Did anyone else have knowledge of them being in his possession? Did he leave them unattended for any period of time? I've seen it reported that he went to work on Monday and shipped them on his break from work, so did he take them to work? If so, where and how were they stored? Did he leave them unattended at his home? By taking the course of action he did, and I'll assume haven taken it completely innocently, it opened a pandoras box of possibilities and numerous chances at making a mistake. You combine that, with Braun's already highly unusual test result and you easily prove reasonable doubt, at which point it becomes impossible to prove guilt or innocence I would think.
