I think having one of the rapes actually happen right in the police station itself goes a long way to explaining the uproar: when rapes can take place almost literally under the noses of the police, they clearly aren't doing a good job of fighting it. (There's a small parallel there - someone recently pointed out that one of the two murders carried out in the US with legally-held automatic weapons since they were almost entirely banned was actually committed by a cop.)
In the article it was said that the police were the perpetrators, the women had refused to bribe them.
