From the HSUS link to the actual charges. http://www.humanesociety.org/assets/pdfs/horse/mcconnell.pdf
I think the dates will carry some weight in the many discussions on these undercover efforts by non governmental entities.
It may all be misdemeanor charges with minimal penalty as the acts took place before Tennessee beefed up their animal cruelty laws. But here is a link from google on the scope of the law:

[INDENT][INDENT] Summary: These Tennessee anti-cruelty provisions define “animal” as a domesticated living creature or a wild creature previously captured. A person commits the offense of cruelty to animals (a Class A misdemeanor) if he or she intentionally or knowingly tortures, maims or grossly overworks an animal; fails unreasonably to provide necessary food, water, care or shelter for an animal in the person’s custody; abandons unreasonably an animal in the person’s custody; transports or confines an animal in a cruel manner; or inflicts burns, cuts, lacerations, or other injuries or pain. It is a defense to prosecution that the action was accepted veterinary practice or bona fide scientific research. A second or subsequent conviction for cruelty to animals is a Class E felony. Animal fighting is also prohibited under this section, with dog fighting incurring a felony penalty and cockfighting resulting in a misdemeanor in most cases. A person commits aggravated cruelty (a Class E felony) to animals when, with aggravated cruelty and with no justifiable purpose, he or she intentionally kills or intentionally causes serious physical injury to a companion animal. Again, exclusions include animal farming, research, veterinary practices, hunting, trapping, “dispatching” rabid animals or wild animals on one’s property, among other things.[/INDENT][/INDENT]
