1. The perp used a hatchet. This means he was not using a gun in the first place. So, he was not as bad of a crook as he could have been.
False premise. A deadly weapon is a deadly weapon. Use any deadly weapon to attempt or successfully commit murder, and you are equally as bad of a crook as any other crook who uses any other deadly weapon to attempt or successfully commit murder.
I missed that the only legitimate death penalty, the instant death penalty in lawful self-defense, was administered by the Good Samaritan. Until the perp comes back as a zombie, there's no need to discuss whether a jury would need to guarantee he will never possess any deadly weapon again. Which no jury as we know it could, as everything can be a deadly weapon, so the safest place to put a living or undead attempted or successful murderer is prison, where he will only be able to murder other murderers, and people who volunteer to guard murderers.
Okay. Anybody can kill anybody passing him while walking down the sidewalk, without much or any training, if the murderer is fast enough.
In our little story, it was assumed that the perp would be taken into custody if he lived. Then, hopefully the jury would do its job in court.
Gun control? Anybody can kill anybody. Place everybody in strait-jackets and let robots feed us and wipe our behinds. That way we won't be able to hurt anybody. How much people control do some naive nuts want?
The jury can do its job in court but ONLY in court, as it cannot control anything further than what what each juror says in their verbal and written verdict. A jury can say "we find the defendant guilty of attempted murder and order him to serve life in prison without possibility of parole, probation, pardon, or commutation" but the government can then immediately release him following that verdict and not only allow him to continue his criminal violence through neglect, but also affirmatively give him instruction and material support in committing more criminal violence.
If the government is the prosecutor in the case, the judge might be able to override the jury to some extent. But if the prosecutor is a man in a common law court of record, the jury has the final say. The judge is only a magistrate, completely separate from the Tribunal - Corpus Juris Secundum Volume 25 Section 344.
