Decriminalize Victimless Crimes.
I understand that the government wants to regulate certain behavior as it relates to addictive/potentially harmful substances and behaviors. Whether or not you agree with that, if someone is exploited by violence in any sort of busimess dealing around that activity, they have no recourse to obtain any sort of justice. Instead, the current system requires that the victims remain quiet as the law is likely to prosecute them for only seeing to their own desires while bringing harm to no one else.
