“If the races were reversed would it even have been prosecuted as a misdemeanor?”
It is not a misdemeanor to wave a gun at a child and threaten to kill them.
Under prosecutorial discretion it can be unprosecuted, pled down, or prosecuted to the maximum.
Was a gun confiscated at the scene?
I ask because the article says, “Witnesses said that another had a gun”. There was no mention if anyone was arrested for a firearm.
