@ Kyle Davis. Speaking as a former deputy sheriff, all applicants to all departments in all jurisdictions MUST have fingerprints and a photo ID just to be considered for employment....but that wasn't the case as recently as 25 or 30 years ago. Also, it's very easy to create a false identity....especially back then.

don't you have to have a blood sample on file or at least finger prints to become a detective?

I'm of two minds on this one. I have friends who have PTSD and there are times where they are VERY emotional. But, they did not explore the complex issue of PTSD. I do understand that shows feel that they have to simplify things for the audience. If Orlando was a scuzzy bum that would have been offensive too. I would have preferred that they made his situation and condition more accurate and complex but I understand that they felt that they had to dumb things down for most viewers and clean things up to be acceptable - that is something that I find annoying on many shows. As for the doctor getting too close to her patients, I think that was part of the point. The doctor had her own problems and that made here make bad decisions.

Dude it's a sci-fi/fantasy show. It doesn't have to be 100% accurate. And PTSD part is so that people do they own homework on the subject.
