“You don’t NEED an Official Courtroom Trial.”
You are making a mockery of the Noachide laws. One of them is to set up a formal legal system. This was an extrajudicial execution. In other words, murder. The officer responsible is now facing homicide charges. He won’t get the death penalty, though, which is good, because as pointed out US courts don’t follow Noachide law. (Minnesota fortunately abolished its death penalty in 1911.) Every execution in the US where there was no eyewitness testimony is homicide and the Governors who sign the death warrants will be called to account.
Essentially, you are supporting murder.
