The students should be congratulated.

‘Seven teenagers who attacked a gang member who went to their school allegedly looking for a fight, took the “law into their own hands”, the school principal says.
The incident, which occurred at Trident High School in Whakatane on Monday, attracted a crowd of onlookers as the man was kicked and punched, the Whakatane Beacon reported.
The 22-year-old victim was arrested for breaching his bail conditions and was trespassed from the school, while two others were trespassed in an effort to calm the situation.
The year 11, 12 and 13 students involved have been stood down and would attend a disciplinary meeting on Friday involving school staff and police youth aid officers…’
They took the law into their own hands because the “law” is effing useless when it comes to dealing with thuggery in a timely, effective manner. I hope there are more such incidents.
