Chelisa Grimes did it after administrators apparently didn't do enough to stop the bullying against her son. The mother says she will do it again -- even though the teen now faces expulsion, according to news reports.
"I do not promote violence -- not at all -- but what is a parent to do when she has done everything that she felt she was supposed to do ... at the school?" said Grimes. "I did feel like there was nothing else left for me to do, but protect my child."
The school district held an expulsion hearing last week but no decision has been announced.
Grimes sent her son to Arsenal Technical High School in Indianapolis with the stun gun after he said he was being taunted and bullied for months.
After six students surrounded him at school April 16, calling him names and threatening to beat him up, he pulled the stun gun from his backpack...sending the group scurrying, he said.
"I brought the stun gun 'cause I wasn't safe," said the 17-year-old.
