Because you’ll have to override a veto, and it will never happen if you decriminalize it altogether. Actually, you would have a better chance if you make the misdemeanor apply only to incidents where the alien was not killed. Make it retroactive. That’s all that would be required to get these guys out of jail.
Good points. Even if vetoed it would serve notice.
As far as retroactive law making, I thought you were only allowed to do that with taxes on the rich?/s
