From what you describe, you might be saving some lives in the future by reporting it. I know too many people that have been killed doing stupid things in aircraft either thru ignorance or willfully actions.
If a firm hand had been placed on their shoulder earlier to let them know people are watching and are concerned, they might still be here getting old and grey like me.
Report it if in doubt.
