It seems to be another law that is blatentley ignored. The local papers report where teh red light areas are, you drive around them and you see these poor, drug addicted, pimp controlled girls that are scared beyond their wits. It sickening that in this day and age we can't admit as a society that prostitution will neevr go away. There will always be people who would prefer, or have to for physical or personal reasons, to pay for sex.
If you legalise it, you can setup proper establishments, give the girls the protection they need and tax it. You'll never be able to stop it so you should offer the girls a safe working environment. This would also protect the innocent girls who walk through htese areas and get approached by strangers wanting them to perform lewd acts for money
