"Signing a piece of paper". Come on, the guy KNEW he was signing for an illegal substance. He even admits that he knew it was wrong when he did it. Those coming across the border KNOW they are breaking the law as well. There is no difference.
If you don't like the laws against marijuana, work to change them. But if you are going to excuse this guy for ignoring a law, then it would be hypocritical not to also excuse the illegals.
What I can’t excuse is your failure to distinguish between someone whose transgression started and ended with a single signature (even knowing it was wrong) vs. people who organize their lives and those of their children and potentially grandchildren, around violating not just one law but many, day in, day out, for the rest of their lives. How long does a signature take? 5 seconds? That’s the duration of the man’s dastardly act.
