As they used to say, possession is nine tenths of the law ! What ever that means. I would kick it around with a 10 ft pole, and if it doesn't explode, open it and keep it or donate to thrift store.
They dropped off a package a block away and the home owner never even looked at the address on it and brought it to me. Amazon ended up replacing it for free but some neighbors sure not very neighborly. I was going to knock on his door and have a few words but who knows what kind of quack lives there.Amazon dropped off the wifes package next door the wife sent me over to get it. It was after dark and I said " ok but this is how people get shot snooping around at night on other peoples porches..."
