That was a retarded response. There were no more violent actions based on prohibition. You can’t argue that there was because prohibition was over. To try to claim criminals simply moved on to other things is a non sequitur. Those things existed before prohibition and were not connected to it in any way. You might as well argue murders still happen so prohibition must not have worked.
And YOU might as well argue that we lift the prohibition against murder. Since tens of thousands of Americans are murdered each year then (according to your logic) laws against murdering someone do not work.
I get it. I understand your liberal logic: There will be no more drug crimes if we pass pro-drug laws. And if murder rates are a problem? Then we just legalize murder too. Problem solved!
