I do not read WW comics and I know her only from JLA comics, so I do not know if the issue was ever adressed in a comic or a thread. As far as I know her lasso forces people into submission or at least forces them to tell the truth. Have ever someone noticed that it is basically mind rape? She is forcing people to do something they do not want to do by breaking their will, which in my opinion is problematic.
We have the American Convention on Human Rights, the Charter of Fundamental Rights of the European Union, the European Convention for the Protection of Human Rights and Fundamental Freedom, the United Nations Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (CAT) etc., which all basically state "No one shall be subjected to torture or to inhuman or degrading treatment or punishment."
I am quite sure that if we had something like the lasso in the real world it would be forbidden in the conventions and in the criminal law statutes and other statutes. But even without an explicit mention it would be forbidden, because the conventions state: "No one shall be subjected to [...] inhuman or degrading treatment [...]." In my opinion the use of the lasso is a highly degrading and inhuman treatment. One could argue that mind rape is even worse than physical torture, because it assaults your most private thing, the only thing you really have for yourself - your private thoughts (and of course your right to remain silent and your right to not incriminate yourself). Is is not different than the use of truth serum, which is considered a form of torture in real life.
I know that WW is not a state and not a policewomen etc., so she is not bound by the rules of the conventions. But should she not respect the idea behind the conventions, should she not respect the standards set by these conventions? How can one say she loves humanity etc. if she breaks one of the basic human rights and mindrapes people with her lasso.
