Dreamer? Nah, Dick Durbin said they are all model citizens who pick our fruit
From that story:
A teacher at the school told the Miami Herald that Cruz, 19, had been identified as a potential threat to fellow students in the past.
We were told last year that he wasnt allowed on campus with a backpack on him, said math teacher Jim Gard, who said the former student suspected in the shootings had been in his class last year. There were problems with him last year threatening students, and I guess he was asked to leave campus.
Gard says he believes the school administration had sent out an email warning teachers that the student had made threats against other in the past and that he should not be allowed on the campus with a backpack. Another student interviewed on the scene by Channel 7 said the student had guns at home.
DACA?
