There are strict rules about when we can see the video.  Since almost all slip and fall accidents occur in a store, they are often caught on closed circuit security cameras.  The video is considered to be work product, and the store will not turn it over until after a lawsuit is filed.  Now, during the pre-suit process, we always ask the adjuster what is on the video, but that is often as much as we are able to learn.  It is a frustrating process, but the law.
