We had an incident in Iowa where a Sheriff used a barricade round to shoot a person that was threatening to kill themselves. The round is not authorized by the department and he was never sanctioned for it. He hit the person in the neck at 40'. He says he was aiming for the stomach. Right. The suicidal person was killed.
A barricade round is not a less-lethal round. Barricade rounds will just plain kill people with a direct shot.
If you mean to say he used a bean bag round, well the older versions of these rounds were bad about veering off course and striking areas that you weren't aiming for.
