Baby is sent through X-ray machine at LAX

Found this while browsing my Internets (originally linked to from here):

A woman going through security at Los Angeles International Airport put her month-old grandson into a plastic bin intended for carry-on items and slid it into an X-ray machine.

The early Saturday accident — bizarre but not unprecedented — caught airport workers by surprise, even though the security line was not busy at the time, officials said.

A screener watching the machine's monitor immediately noticed the outline of a baby and pulled the bin backward on the conveyor belt.

The infant was taken to Centinela Hospital, where doctors determined that he had not received a dangerous dose of radiation.

Officials, who declined to release the 56-year-old woman's name, said she spoke Spanish and apparently did not understand English.

She initially didn't want the baby transported to a hospital, but security officials called paramedics and insisted that the child be examined by a doctor.

The grandmother and the child were subsequently allowed to board an Alaska Airlines flight to Mexico City...

So I have a few questions:

1. What was she doing in the US and why does she know no English?
2. Does this speak to how screwed up California is?
3. How would speaking English have kept her from putting a baby through an x-ray machine?
4. Do we now need to put anti-baby indicators on x-ray machines (such as a crossed out silhouette of a baby)?
5. Why is this "bizarre but not unprecedented"?
6. Why is she flying Alaska Airlines to Mexico City?
