"And, by the way, the biblical standard is that one only need two witnesses to establish a foundation for clear issues."
Two witnesses which qualify... maybe that is a discussion for another thread?
Because we also have this:
Exd 23:
1Thou shalt not raise a false report: put not thine hand with the wicked to be an unrighteous witness.
2 Thou shalt not follow a multitude to do evil; neither shalt thou speak in a cause to decline after many to wrest judgment
7 Keep thee far from a false matter; and the innocent and righteous slay thou not: for I will not justify the wicked.
Deu 19:15 One witness shall not rise up against a man for any iniquity, or for any sin, in any sin that he sinneth: at the mouth of two witnesses, or at the mouth of three witnesses, shall the matter be established.
16 If a false witness rise up against any man to testify against him [that which is] wrong;
17 Then both the men, between whom the controversy [is], shall stand before the LORD, before the priests and the judges, which shall be in those days;
18 And the judges shall make diligent inquisition: and, behold, [if] the witness [be] a false witness, [and] hath testified falsely against his brother;
19 Then shall ye do unto him, as he had thought to have done unto his brother: so shalt thou put the evil away from among you.
20 And those which remain shall hear, and fear, and shall henceforth commit no more any such evil among you.
Deu 17:4 And it be told thee, and thou hast heard [of it], and enquired diligently, and, behold, [it be] true, [and] the thing certain, [that] such abomination is wrought in Israel:
5 Then shalt thou bring forth that man or that woman, which have committed that wicked thing, unto thy gates, [even] that man or that woman, and shalt stone them with stones, till they die.
6 At the mouth of two witnesses, or three witnesses, shall he that is worthy of death be put to death; [but] at the mouth of one witness he shall not be put to death.
7 The hands of the witnesses shall be first upon him to put him to death, and afterward the hands of all the people. So thou shalt put the evil away from among you.
8 If there arise a matter too hard for thee in judgment, between blood and blood, between plea and plea, and between stroke and stroke, [being] matters of controversy within thy gates: then shalt thou arise, and get thee up into the place which the LORD thy God shall choose;
9 And thou shalt come unto the priests the Levites, and unto the judge that shall be in those days, and enquire; and they shall shew thee the sentence of judgment:
10 And thou shalt do according to the sentence, which they of that place which the LORD shall choose shall shew thee; and thou shalt observe to do according to all that they inform thee:
11 According to the sentence of the law which they shall teach thee, and according to the judgment which they shall tell thee, thou shalt do: thou shalt not decline from the sentence which they shall shew thee, [to] the right hand, nor [to] the left.
12 And the man that will do presumptuously, and will not hearken unto the priest that standeth to minister there before the LORD thy God, or unto the judge, even that man shall die: and thou shalt put away the evil from Israel.
13 And all the people shall hear, and fear, and do no more presumptuously.
