So which is it, Mexico: are your nationals subject to the jurisdiction of the U.S. Government or are they not? You can't have it both ways.
If they are, then your claims with regards to these rapists and murders are full of excrement. If they are not, then all those anchor babies were improperly awarded U.S. citizenship. Either way, the Mexican government is encouraging an invasion of our States -- an act of war -- and our own Government is standing by and doing nothing, an act of treachery against We The People that is so great that it may merit a Revolution, whether peaceful or otherwise.
Just because some Mexican forgot to get a visa doesn't mean that requirement can be forgotten.
American citizens, BTW, do not need to be added to anyone's visa.
There are tens of millions of people here claiming citizenship based on their anchor baby status who are simply not aware that their true status is that of stateless alien awaiting addition to their momma's visa!
