Sex trafficking has been used as a in a moral crusade to end prostitution. Justice Minister David Ford does not believe criminalising the purchase of sex will reduce trafficking. He believes criminalising the purchase of sex will endanger sex workers. Research conducted by Queen’s University found 61% of the sex workers they surveyed in Northern Ireland believed criminalising clients would make sex workers less safe, and 85% did not believe that it would reduce trafficking. Indeed, UNAIDS has found that criminal laws related to sex work increase danger for sex workers.
