My question involves criminal law for the state of: All states?

If undocumented aliens are not seen as persons - have no personal rights - under the law [as explained by Noam Chomsky, Commonwealth Club, CA, 2009], is hurting or killing an undocumented alien not assault or murder in the eyes of US law?

The aim is to clarify : Under what juristictions are "undocumented aliens" equalling "not persons"?
- Just regarding denying them healthcare, or is the definition judicially universal?
