We always bring ours in when I turn our lights out around 9pm on Halloween just in case. I wouldn’t really mind them getting stolen since they just rot in another day anyway but some people smash them which is a huge obnoxious mess.
On our NextDoor group there were 2 very hot threads started yesterday because of Ring doorbells. One person captured an adult man, at least 30 years old, taking all of the candy left out from a ‘help yourself’ bowl. The other thread had a video of a little girl going up to a ‘help yourself’ bowl and having a conversation with the mom further back who coached the girl into taking all of the candy AND the bowl (the little girl had more of a conscience about it than her mom did but did what she was told).
