As mentioned below, birdshot is really not that dangerous when it is coming down from its apex. Unless maybe it hit you in the eye. I've had shot fall on me goose and duck hunting before. Not worse than hail. In a situation like a max-security prison, where you've already got cleared dead spaces around it to shoot escaping prisoners, its not really an issue.
