The art teacher who threatened to carry out a Columbine-style attack on her Brooklyn high school says she simply “wasn’t thinking” when she made the loaded remarks.

Sabrina Milo, 34, was “just venting” when she told a Fort Hamilton HS colleague in the teachers’ lounge, “If I had a shotgun and a trench coat, it would be Columbine all over again,” according to an interview the disgraced educator gave last night to WABC/Channel 7. Milo, of Staten Island, was arrested last week and charged with making a terroristic threat. She is free on $100,000 bail.

“I had no intention of doing anything harmful to anybody.”
