I don't know about Alabama, But in Arkansas removing of flowers and such decoration from graves by anyone other than maintaince personal, for the purposes of mowing, or the family, I believe is illegal. I think it is called Theft of Property. The lady, since she saw this, should go to the Auburn City Attorney and charge this Councilman criminally. If the roles were reversed I am sure this councilman would do the same. Motivation is not an excuse for violations of the laws even if it does offend him.
It would be a good penalty for this councilman to have to decorate these Graves every Confederate Memorial day for lets say the next 10 years.
