How is she a teacher?

Stuff reports:

A teacher yelled racist abuse at an outnumbered group of police officers dealing with an aggressive crowd of Mongrel Mob members. …

Police were attempting to calm the situation when Morrison arrived, driving her Suzuki Swift through the group of police and others.

Morrison got out of her car and began to enflame the situation, yelling racist abuse at several of the officers, who were at that stage trying to leave the area due to being outnumbered.

When Morrison was later arrested she admitted her poor behaviour and apologised for her racist slurs, but not for attacking the officers.

It goes without saying that she should not be allowed anywhere near kids and a classroom.

Judge Sygrove noted Morrison had three pages of previous convictions.

How did she get registered in the first place?
