Um… You guys created the precedence when you decided that state could ignore federal immigration laws. Good luck.
The DoJ is probably ‘technically’ right, but that does seem a little two-sided. I think states / cities decided NOT to enforce federal laws on immigration / marijuana enforcement, but I don’t think the states / cities legally BANNED their enforcement. I could be wrong and it’s duplicitous either way.
So the states can ignore the law or not enforce them, kinda the opposite of “preemption”, but the feds could go into the state and enforce them like they did with medical mj in CA under the Obama admin. I’m no lawyer but that is my take.
