Chris wrote: As has been discussed on the list in the past, almost all evidence maintains integrity only by someone testifying that it is as it was. In pictures especially, since photos have been manipulated since they have been around. (Flying saucers, big foot, etc.) There are only a few places where a photo stands by itself in court. Examples: Photos taken unattended by an ATM machine of someone using a stolen card. Or where a photo is introduced as truth in a liable suit. Both of these must be verified as being real. Then all the 'experts' come in and try to prove one way or another. However most photos are sworn to as being a 'resonable representation' of what was observed by someone, such as the lab tech or investigator. We mainly show the investigators how to do the same things that were done in the lab before. If a lab tech took a picture that was under exposed, they would 'fix' it so you could see by burning portions in, not changing what was there. Just now, the investigator can do those things to see more detail, etc. -- Jerry McCown Law Enforcement Training Coordinator Informational Web Sites Law Enf. Training: GCCLEO.COM Law Enf.
