On reading today's Sunday Times feature on the foam spray menace, I was disturbed at the readiness of Singaporeans to attribute sexual rapaciousness to foreign workers (presumably Indian or Bangladeshi construction workers). Consider:

Though victims largely point the finger at foreign workers, police said the eight arrested were a mix of locals and foreigners.

and:

Marketing manager Teo Shuyin, 21, who was on Orchard Road last Saturday, recalls walking with her arms folded across her chest. She said the culprits were foreign workers.

'They set on us the moment we stepped out of the car. I was hiding behind people and using my arms to cover my chest. And even when they weren't spraying, you could feel them staring at you,' she said.

Of course molestation is wrong, but how can Singaporeans be so sure that the culprits aren't locals?
