The guys at Reason magazine (the Libertarians) have consistently suggested that if you are having problems with a person you love, the last option to consider is to call 911 to “get them help”.
A woman was with her mentally ill brother, an immigrant from a Uganda, at a Mexican restaurant when he started acting erratically. Keep in mind, the bar for people calling 911 has fallen to complaints at the drivethru that their McNuggets are not hot enough.
So the loving sister turns on her Facebook livestream and calls 911. Having committed no crime, having no weapon and no imminent threat, the man was executed by police for failure to obey a police person’s lawful order. He behaved like he had a gun, taking a shooting stance, but with no gun.
The priority in these decisions is that the police officer goes home safely to his family. In this specific situation, there was no dog to shoot, so it could have been worse.
