Until I know what set off this child’s tantrum, I will not pass judgement on her actions.
Students breaking glass, attempting to throw broken glass, choking out other students, trying to cut themselves with tacks, hitting, kicking, and biting staff. And some have been kindergartners up to 5th graders. Several have been admitted to in-patient psych units. One parent told of the student approaching his 7 year old sister with a butcher knife. They put bells on his room door so they know when he is "coming out" into the house.
Save all your sanctimonious condemnation of the police and school system. You obviously are ignorant (in the literal sense) of modern reality.
Believe it or not, some children (particularly those who were crack addicted or with FAS) need NO trigger for a tantrum. It could be as simple as ‘she looked at me wrong” to being told to sit down to anything.
This behavior from a six year old is out of proportion and indicates that she is developmentally behind OR she uses this crap at home and it works.
Children who have parents that do not tolerate tantrums do not have this problem UNLESS their child has some other underlying organic problems.
