From the article.... " We took close to 40 young ladies off the street. We saw them walking on the streets, scantily dressed, and unable to give a proper account of why they were out in the street…,” Senior Superintendent Steve McGregor, commander of the St James Police Division, told reporters.

“In fact, those that we took in were arrested on reasonable suspicion because if we see a person scantily dressed and cannot account for what they are doing it is reasonable to think that these persons might be of the intention to commit a crime."

Bravo.. you could never apply such common scene policing in the US, because we're do wrapped up in political correctness. 40 lawyers would be appointed and they'd go after damages to the prostitute(s)
