Child Safety

I saw a report about a 3 year old Mexican child who died in the desert. He was trying to enter the country illegaly with his mother, who abandoned his dead body. She was caught by the Border Patrol and arrested, at which time she told them about her dead child.

Don't we frown upon endangering the welfare of a child? Isn't it illegal to leave a child unattended? We don't look too highly upon people who use children in armies because they are placing them in a dangerous situation. So why should this be any different? Perhaps this is yet another difference between our culture and that of Mexico. Maybe after they change the official language of the United States to Spanish they will allow parents to endanger the welfare of their children. Who knows what will be next?
