There might be muscle damage although minor it could happen, I got tagged quite badly by a 10 foot albino burmese once badly (was all my fault ) and it got its teeth just right on my hand that they went through my muscles in my fingers, nothing that time did not heal and nothing permanent came out of it but there you go. I do not recommend people bring their animals out for a jog or to the local schools frequently unless you know what you are doing and you NEVER release the head of the animal that is just a law suit waiting to happen it does not matter how tame your burm, corn, king ect is .. these kids are unexperienced with these types of animals and jump and scream and ocasionally run and try to drop the animal so for not just the sake of the child for the sake of the reptile as well keep ahold of them that way if someone does freak out and try to run or get away you still have some element of control. Kids almost always freak out whether out of excitment or fear.
So please anyone who thinks they can just take there reptile to a local classroom remember this because if one child gets bit do you EVER think that anyone will be able to educate with reptiles in school again? No the board will vote against it we as educators have to debate enough to have them in the schools so we can root out the ignorance in pepole.
Also I think that that officer handeled the situation quite well and must have been an educated man in herps to some degree to realize that boy that was holding bunnies= nice snake snack.
