Why in CSI do they always use just torches to look for evidance?!
Question: Why dont they just turn on the light.
Answers: Why dont they just turn on the light.
Depending mostly on the condition of the crime scene. Most of the time, it's a dramatic effect for the show.
Other times, you see a filter attached to the torch to help show other evidence that may be hidden from the normal sight.
Eventually they're going to flip the switch, dusting it first of course, otherwise the battery is going to run out of power for the torch.
Because unjust torches can produce biased evidence.
Maybe because the whole thing is rubbish and the producer knows that flipping a light switch wouldn't be as dramatic as torches in a dark room?
To make it seem more freaky?
could be finger prints on the light switch? or the fact that such a small beam of light tends to focus your attention on just that little area - less chance of missing something
They are looking for evidence from the Dark Side. Turning on the lights does not work, because it destroys the atmosphere that the director is so carefully trying to create.
because they are trying to make it look realistic as possible, a real c s i would not go into a crime scene and touch things without looking at it carefully first incase of contamination.
because if your investigating a crime scene you have to leave it exactly how you found it, so if the light is off when you arrive at the scene, you leave it that way, otherwise its tampering with evidence really.
You could spend a lot of time questioning the discrepancies in c.s.i.,how about why when Horatio (csi miami) detonated a bomb "twice the size of the oklahoma bomb", which was a few hundred feet away did it not even ruffle his lovely ginger hair ? and why the hell would a crime scene investigater be shooting a truck load of explosive anyway?(still i am a big fan anyway) to answer your question i think maybe they don't want to compromise any prints on the light switch,probably. If you want an american cop drama with an ounce of realism you should watch The Wire, it's brilliant and believable too.
There are different types of torches to look for different types of evidence. They need ultraviolet lights too see things that are naked to the human eye and they need torches that do not create a shadow.
If you mean the little blue torches, they're ALS lights which can pick up proteins and illuminate them. They can find blood that's seemingly been washed away.
If you mean regular torches, I think it's so they can get the light at the right angle to see things, if they used the light at the scene there may be shadows which could obscure the evidence.
I have a friend who does some of this work, and he tells me that it helps to focus on specific areas, rather than to look at an entire scene at once. Obviously, in the real world, the DO look over a scene as a whole as well, but when it comes to finding fine details, a torch/flashlight helps narrow one's focus.
With all the lights off!! That always irritates me. lol
Haha.... I've always wondered about this. I think it's because:
1. Flipping the switch would destroy fingerprint evidence on them if there were any in the first place
2. It seems more dramatic and freaky to just walk in the dark with no light except the one from your torch
