For anyone who wants to read Plyler vs Doe decision, a narrow 5-4 decision with the famous Chief Justice Warren Burger, Justice Byron White, Justice William Rehnquist and Justice Sandra Day O'Connor, dissenting.

This case has absolutely ZERO impact or effect on federal authority to swoop into schools and start loading up illegal aliens of any age for deportation. Illegal aliens have absolutely NO PROTECTION from deportation procedures while at a school or anywhere else.
Plyler vs Doe requires a state school district to admit them for educational purposes, it does not protect them against any action by the federal government or any state action required by the federal government. NONE.
I don't know why some are trying to put protections where they do not exist. There is no place within the United States that is a "safe place" or a "sanctuary" for an illegal alien of any age for any purpose.
