A site inspection can decide how a case is understood. If the inspection is only attended and not filmed well, key details can be missed, disputed, or forgotten. A store aisle after a slip and fall. A rural intersection after a crash. A damaged roof after a storm. A subject vehicle after impact. A construction site with alleged defects. Each one can change fast. Photos help. Notes help. But video captures location, sequence, scale, movement, and the work performed by experts.
