Dexter's job/ Blood Spatter question?

What are you asking? If real blood splatters are being judged thru Dexter, what do you mean, like real police and/or detectives watching Dexter to help them solve their blood splatters? If that's what you meant, then no. And then you ask are "they" suspicious nowadays? First who is "they", police? and who are they suspicious of Dexter? Or real blood splatter anaylasis' workers?, why would they be suspicious, because a fictional tv character is a serial killer? That's another no. Real blood spatters have been anylyzed and helped to solve murders for a long time before Dexter was ever on tv. I'm not sure if that's what you meant.
