Stats about illegals are very skewed. They only deal with CONVICTED. Problem is, that for real crimes short of murder, illegal is sent home ( and will return later ). For minor felonies and upper misdemeanors, they move down to low-end misdemeanors so as to not deal with BS ( ag trespassing for car theft? Gads ).
And those who murder, hide in community or go home.

So no, these stats are worthless.
