Do you mean the "Bucha massacre" that has never been proven. The one where Russia asked immediately (within days) for an objective UN investigation, and the UK, supported by the US, immediately rejected the request because at the time the UK was the rotating head of the UN security council? That "massacre?"
The longer this horible war goes on, the more evidence comes out that supports my position: There are no "good guys" in this war except the average Ukrainian citizens and conscripts on both sides. Russia is not good, Ukraine is not good, and the US /UK is/are not good.
