AP story: 3rd-graders aimed to hurt teacher

I'm Sub. Teaching until i graduate and i usually get 5th or 6th grade kids and i just couldn't imagine kids younger than that doing something like this... i guess i don't Sub. in ATL. more like Gulfport, Biloxi, Ocean Springs- not necessarily bad neighborhoods, but seriously these kids all seem so young and innocent and willing to learn, i think some of these teachers go to far with these kids and force them to violence....
