I am sure most of you have seen the TV shows "CSI" (Crime Scene Investigation) or either of its spin offs "CSI: Miami" and "CSI: NY". What I don't understand is why do they always work in the dark at the crime scene? If you have not notice, each time they are in a house or apartment, they never turn on the lights but use their flashlights to search for and find the most minute evidence.
I do understand that the light switches and lights themselves are possible evidences, but wouldn't they process those first so that they can lite the room?
Another thing is, how come they are not wearing full body suits to avoid contaminating the scene? I've noticed other criminalists, the ones who are not the leads in the show, do indeed wear full body ("white") suits.
I think they should be as accurate as possible for the simple things in the show, especially when some of the technologies used are simply Hollywood magic.
Having said all that, "CSI" and its sister shows "CIS: Miami" and "CSI: NY" are all my favorite TV shows.
