Do they make a rail mounted camera for guns? Here's my idea. Attach a small digital camera to the rail of a gun and have it be activated either by the trigger pull which might require extensive modifications which could affect reliability of the weapon or have it activated by movement of the slide. Basically every time the slide starts to move a picture is taken. I don't know if muzzle blast would block the view but if not this would be something I think could be used by LEO to show exactly what they were shooting. Could be used as both a legal tool to prove the facts in a case but it could also be used as a teaching tool showing a person exactly what their sight picture really was when the trigger was pulled. Thoughts?
