MRM presents a fine case that tugs at our emotions and paints a narrow picture only of the effects of ILLEGAL prostitution. We already know illegal prostitution puts women at risk. Actual data and studies suggest he is at least partly wrong about the effects of legalization.
Legalized, regulated, educated, prostitution in NV offers greater protection to women than illegal street prostitution run by organized crime. It also reduces human trafficking, disease and violence among those who work legally in the trade in NV. Studies show that the regulatory model in Nevada offers the highest level of protection for women who work in the sex trade. These successes are not universal however and in some countries with more lax regulation or corruption, results of legalization are mixed.
