I understand what you are saying, and I'm not arguing that the enforcers are even acting within the limits allowed by law. But in the general case you cited, the enforcer's error and mistreatment depends on some action in a courtroom.
And assuming for the sake of argument that there are cases where atf denies approval, and the only thing on the record is an arrest (no conviction, or even a finding of innocence, or even an opportunity for hearing), my point was mostly one of legal grammar. A "sentence" is handed down by the court or a quasi court. Denial of approval is not a "sentence" in the vernacular.
Triggering the felon in possession law requires a sentence, imposed by a judge.
Gotcha.
Damn sure are some folks here I’d love to have a drink with while discussing these tricky issues.
This is a great topic.
