I'm really annoyed by dummies who take the last shred of credibility out of their roles. I only wonder who did the research? These examples would never be allowed to work in their posts in real life. In comparison, I have taken few pics from a Canadian show that does it as it should be done, has done its background work and receives kudos for other merits as well.
THE GUILTY EXAMPLES
CSI: Miami, dr. Alexx Woods
I always wonder how many hairs she has left in multiple crime scenes. If she wanted to murder somebody it would be easy because nobody would pay any attention to those hairs in pillows, floors... etc. The whole presence is otherwise incredible as well.

NCIS, Abby
Pic tells everything. Yes, she dresses up that way for work. I have no idea why I watch this crap ..
HOW IT SHOULD BE DONE



More convincing, eh?
