Neighbour 1 who lives opposite us had his driveway semi-blocked by neighbour 2 who lives a few doors down. Neighbour 1 got extremely angry and started shaking and kicking the car. He was shouting saying "I'm gonna * scratch the car" etc etc. Neighbour 2 apologised and moved the car and Neighbour 1 went back into his home. My BIL messaged neighbour 2 who we're friendly with asking what happened and he said his car has been scratched by neighbour 1. He asked if we had evidence. Our Ring doorbell recorded everything. If BIL sends the evidence then it's obvious it came from us as our driveway is visible. If BIL doesn't send evidence then there will be a dispute between neighbour 1 and neighbour 2. What would you do? Is it morally right to get involved?
