Ok - have name changed for this one as is so specific.
Neighbor phoned me this morning to say that the builder who is currently working on her has has reported that her next door neighbor's teenage son has a gun (air gun / bb gun - she couldn't be specific) - and is doing gun practice in his front garden - appears the boy is missing more than hitting his target and those missing pellets or whatever they are land in my front garden!
She just wanted to make me aware of situation as I have a young son who plays in our front garden sometimes
I haven't witnessed anything and can not see evidence of it in my garden - but would I particularly see these things
What do I do?
