Now that's what I call discipline!

How do Malaysian schools keep their students in line? Show them what it's like to be whipped!

Flogging Officer Number 1" Iskandar Zulkarnain Mohamad Radzi, 25, from Taiping Prison in northern Perak state, staged the first session on a dummy strapped to a frame before about 300 students at a local school this week.

The pupils, who were also shown photographs of the injuries inflicted by caning, told the New Straits Times they were shocked by the severity of the punishment, imposed for a wide range of crimes in Malaysia, including under-age sex.

Radzi has been whipping convicts for seven years after being taught how to swing the 1.09-metre (yard) cane at a minimum speed of 160 kilometres per hour (99 miles) and produce a force upon impact of at least 90 kilos (198 pounds), he told the paper.

Before he canes a prisoner, he dons a surgical mask to protect his identity and also to prevent bits of skin and flesh hitting his face, the daily said.

Even the most hardened gangsters cried out in pain after the third stroke and those made of lesser stuff soiled their pants after the first lash, he said.
