90 years ago: Protestant pastor in Georgia is convicted of libel against Knights of Columbus

Thou shalt not bear false witness against thy neighbour. Exodus 20:16

But speaking the truth in love, Ephesians 4:15a

On November 30, 1928, it was reported from Savannah, Georgia that Rev. W.F. Larowe had been sentenced to three months in jail after being convicted of criminal libel in connection with the circulation of a false oath of the Knights of Columbus. His sentence was probated after a recommendation of the jury for extreme mercy.

I don't know the details of the case, but I do know this: no matter how opposed to the true Christian faith and gospel an individual or organization may be, if you're going to make and/or circulate a public accusation against them, you should be able to back up your accusation with at least enough evidence to avoid conviction for libel.
