There is no "typical" sentence for anything in Georgia. Sentences given for crimes in Fulton County (Atlanta) are usually much less than elsewhere. Some counties are well-known for long sentencing (Forsyth, Dawson, Cherokee, Walton, etc.) A lot depends on who the Judge is for the case.
FIrst degree Arson carries a minimum of 1 year, maximum of 20 years; up to $50,000 fine.
Aggravated Assault carries a minimum of 1 year, maximum of 20 years;
"Cruelty to a person 65 years of age or older" carries the same sentences, 1 - 20 years
