When I saw that Ray Clark had a public defender and not a private attorney, I can see that the odds are strongly against him. Not to say that public defenders are incompetent. You're basically forced to take whoever has been given to you, versus hand picking your own attorney with a good track record.
The evidence that has been leaked provides strong insinuations of guilt, but I agree that the fact the suspected crime scene (i.e. the whole lab area) was contaminated when it wasn't sealed off. Does anyone know if there were police or investigators posted there after hours to make sure people weren't sneaking in there and doing anything suspicious? Or did all the police leave after a certain time of day?
The DNA evidence could have easily been transferred from daily routines, but also, if Ray Clark left his scrubs in an unsecured location, it could have been used by someone to contaminate the evidence. We don't know because they just focused on Ray Clark. The bubble gum, fishing hooks, etc.. in the bag isn't even strong evidence of him doing anything with that. Same thing with him allegedly trying 'hide' equipment that later was found to have blood. If they saw him moving it, they might have interpreted as hiding because they suspected him, whereas if he wasn't a suspect, it would have been interpreted as him cleaning up because that was his job.
A lot of the leaks to the media have come from unnamed sources. We don't know how much of it is legit. And if all this leaking is meant to sway the public into automatically accepting Ray's guilt. It's very disturbing if you can put yourself in his shoes and you didn't do anything but the public thinks you did.
