I just happened to type "prostitution" into google and came up with this :
Psychiatric times "Prostitution is sexual violence"Regardless of prostitution's status (legal, illegal or decriminalized) or its physical location (strip club, massage parlor, street, escort/home/hotel), prostitution is extremely dangerous for women. Homicide is a frequent cause of death (Potterat et al., 2004).
It is a cruel lie to suggest that decriminalization or legalization will protect anyone in prostitution. It is not possible to protect someone whose source of income exposes them to the likelihood of being raped on average once a week (Hunter, 1994). One woman explained that prostitution is "like domestic violence taken to the extreme" (Leone, 2001). Another woman said, "What is rape for others, is normal for us" (Farley et al., in press).
Of my own family , my Mum worked with children of prostitutes and no surprise they were frequently abused...but in every case extremely neglected.
From Wiki :
Internationally, the most common destinations for victims of human trafficking are Thailand, Japan, Israel, Belgium, the Netherlands, Germany, Italy, Turkey and the US, according to a report by UNODC, [16] which proves that the link between organized crime and prostitution remains always very strong, whether prostitution is legal and regulated, decriminalized or illegal.[original research?]
I think like that doctor that wrote the piece for the psychiatric times that prostitution is not something that can be made perfectly safe - for either the practititioner or society - the best that can be hoped for is that is minimized as much as possible.
