The original St Pete Times article actually had the professors that teach education to teachers review the tape. The teachers were praised for how they handled the situation. The professor actually gave the teacher an A+ for how the situation was handled! Teacher followed approved methods to the letter.
If you've seen the tape, this answers a lot of questions about education today. Teachers either have no ability to discipline or have no permission to discipline. All "this is not acceptable" bs isn't getting the job done.
