Are witnesses important in a New York trip and fall case?

Yes, witnesses are always important in any kind of a case, because it's important to prove what the defective condition was, and how you were injured. Now, in a trip/fall case, very important as well, are photographs. Photographic evidence of the defective condition taken the proper way. And if you're not in a position to take the photographs at the scene, then you should make sure that you do as soon as you can, because that can make or break the case, because if you can't prove the defective condition you can't win.
