Pg 12 Flashcards
What are some possible problems that can arise in the process of trying to authenticate a photograph?
Lighting, camera angle, differences in position between the event and the photo, pictures intentionally doctored, different purposes that the picture is being offered for, etc.
How can lighting present a problem when you’re trying to authenticate a photograph?
Can make visibility lower or better than it actually was when the event happened
How can camera angle present a problem for authenticating a photograph?
Lenses can alter the perspective or give an odd angle so that the jury has a false impression about the distance or the relationship between the objects and their positions
How can differences in the position between the event and the photo create a problem for authenticating a photograph?
If the event happened in the daytime and the picture is at night etc.
Is it assumed that a picture has been intentionally doctored when you’re trying to authenticate a photograph?
No, it is assumed that the picture wasn’t intentionally doctored unless there’s specific evidence to suggest it
Why is it necessary to consider the purpose that a picture is being offered for when you’re trying to authenticate a photograph?
If an accident happened in the summer where a leafy tree obscured the defendant’s view, and the picture is in the winter where the view is fine, that can affect how fair and accurate the picture is and make a picture misleading. But if the purpose of the picture is just to show the general layout of the intersection, it is fine.
What is the requirement of a witness when you’re trying to authenticate photograph?
The person does not need to be the one who took the picture to authenticate it, he just has to have familiarity with the scene in the picture. This means he doesn’t have to have ever seen the picture before, he just has to be familiar enough with what the picture is of to have a basis in personal knowledge to say that the picture fairly and accurately depicts the original scene
If a photograph was taken in the daytime on a clear day of an accident scene using a fisheye lens to show the width of the intersection, is that objectionable when you’re trying to authenticate the photograph?
Yes, because the purpose is to show the width of the intersection and the fisheye lens distorts that
What are the potential problems that can come up when you’re trying to authenticate a video?
All the same ones that come up with pictures, but also a question about whether the video is just a portion of a whole which would make it misleading or if the video is spliced together to misrepresent events
If you’re going to do an in court demonstration to show the jury what happened, what is necessary?
You need foundation that the parameters of the demonstration bear a fair and reasonable relationship to the underlying events and are done in circumstances that are similar enough to fairly infer something about the underlying events from the demonstration
Would it be permissible to smash a watermelon with a sledgehammer in court to demonstrate what happened to the victim’s head in a car crash?
No, that would not be a fair and reasonable representation to what actually happened for the jury to infer something about the underlying events from the demonstration
What kind of situation would you use a computer model or simulation that would need to be authenticated?
If a plane crash had a black box so you wanted to pair it with digital visual reconstruction of what happened to the plane
What are the two issues for authentication of a computer model or simulation?
– The reliability of the program that was used to change the data into images or sounds
– the reliability of the data itself that was inputted into the program to make the simulation model. It must be from someone with knowledge and it must be a reasonably reliable form
When is an objection to authentication considered to be premature?
If it is raised before the document is offered into evidence. The document must actually be offered into evidence before an authentication objection can be made.
If opposing counsel is in the middle of asking questions to lay the foundation for an exhibit, and you make an authentication objection, what will happen?
It will be overruled because it was premature since the document hadn’t actually been offered into evidence yet
