you are not entitled to claim on your own authority that something is documented on film then add that claim to the article without a reference especially not a criminal allegation and especially not regarding a living person even if the claim is correct there's the question of weight and appropriateness for the article which is about the band and not one article i suggest you find judicious reliable sources and make a neutral statement in the article until then unreferenced claims violating wp blp can be removed summarily and if you continue to edit war you can be reported to both the wp an and blp notice boards
