...execution would be mandatory within 30 days of the perp’s apprehension.

I would prefer a trial and conviction before an execution.

Thirty days sort of works for me - except that I do not trust the current "Justice" system can or will correctly identify perpetrators. Quick executions would most likely be reserved for political opponents of the Regime, rather than ordinary criminals.

It does make me cautious about calling quick action with a rope and a tree.

In any case, I was under the impression that the perpetrator in this instance killed himself and saved the rest of us considerable aggravation.

Yes, as I said, trial, sentencing (and assuming a guilty verdict, of course) then execution.
