A Noahide named John Adams once said that, due to his religious beliefs, "I almost had to change my career" due to being a criminal attorney. One problem Adams would face as a prosecutor is using circumstantial evidence to convict defendants. As a solution, he decided to "switch sides" and become a defense attorney. The article appears here:
Was Adams's actions necessary? Can Noahides work at DA offices that obtain convictions through circumstantial evidence?
I've only received one answer so far, and it confuses me: The answer seems to suggest that circumstantial evidence can result in punishment, just not capital punishment. However, Devarim 19:15 seems to suggest all convictions require two or three witnesses. Then again, Leviticus 5:1 may allow for "witnesses" to include forensics experts, at least if "knowing" a matter includes "knowing" from examining forensic evidence. I would like some more information on this, especially since the answer affects whether or not Noahides can even serve as criminal prosecutors in many jurisdictions.
