The States should stand up to the Feds and the fact that the Feds or the IRS do not raid or arrest call girls,massage parlors, brothels, and organized prostitution in Nevada, which all of the above careers are considered class X felonies anywhere else that will and can get you more prison and parole time than growing weed shows and proves "Yes, we can make the Feds respect our new laws on legalizing cannabis use just as the Feds respect Nevada laws that legalize organized prostitution and sex for sale there". That is what should be used in the Courts to defend Amendment 64. The Feds cannot be seen to be arbitrary about what they raid, arrest, and prosecute especially in a Federal Court. So Colorado can easily and successfully defend Amendment 64 just using the "legal prostitution" of Nevada that the Feds have ignored for 60 years it seems to me. Other States have local laws that defy Federal laws or Federal mandates and have had no reprisals in raids, law suits, or prosecution by the Feds as well. All of these cases of 'arbitrary enforcement" can be used against the Feds power to act here in Colorado and Washington is my belief and hopefully the lawyers representing Colorado/Washington make that a big point to any Judge/Judges overseeing any Fed suits or actions against Amendment 64 or I-501.
