CSI: Why examine a crime scene with flashlights?

HowardPaul · 08-13-2006, 10:12 PM

I've yet to understand why the investigators always seem to examine a darkened room with flashlights rather than turn lights on. This occurs regularly in both CSI and CSI Miami.
Anyone know why? Is there a good reason for this?

I'm just taking a guess here.....maybe they still have to check the switch for fingerprints......or perhaps because it just looks cool on TV.

That is, indeed, the answer.

Next time someone loses an earring or something on your floor try looking for it with a flashlight instead of just relying on the room lights. You'd be surprised how much it helps.

But, the "looks cool" answer is probably just as good.

The reason is very simple, it makes you focus your vision where only the light beam shines.

Also in the case of crimes that you don't know the nature of the light switch might be rigged. In the case of tweeker houses (which Miami does a fair bit with) they often do weird things with everyday objects.

Flipping the switch also disturbs evidence on the plate itself and as was said before using the flashlight focuses the vision on where the beam is shining.

I too was wondering about this. It seems completely unrealistic.

What bothers me more is how dark the CSI Las vegas office is. I mean, has anyone ever seen a gov office that isn't flooded with florescent lights?

And even their lab is dark. A lab without adequate lighting is dangerous.

I think a couple of slot machines would brighten the place up. I mean they have them in the airport and even in a Denny's.

Travis is correct: this is the look of CSI--it is cinematic; not realistic.

I would think that all the possible reasons for the use of flashlights are acceptable, believeable answers.

During the first couple of seasons it looked MUCH more realistic. Even in the clothing they wear. Now they all look like mashion mag models.

Here is what I got from a search of the CSI Forum:

"When they're going over the scene, they have to leave it exactly as it was left when the crime was committed (well, when the perp left). It allows them to better reconstruct the scene so they can figure out what happened. Plus, like previously mentioned, it helps to catch evidence that might not be seen otherwise. Kind of like why the photographers use flash on their cameras as well.

This means that they can't turn on the lights (as well as with those other reasons), they can't open exterior doors (shouldn't, really), open windows (again, shouldn't) or turn off a television without (well at least someone) first noting that it was on/open/closed/whatever and then why they did this action. Plus, if they wanted to do something like that they would have to do that (for example, open a window) like no one else would open a window. Latex gloves can still smear prints, y'know?
Another reason might be is that they are supposed to be the night shift. Flashlights are essential for night shift folks. Also, they do not want to disturb any fingerprints that may be on the light switch. And some of the flashlights have filters to see some bodily fluids. "
