"The students were silently protesting against current tuition practices at the university, which don't offer illegal immigrants who attended Michigan high schools in-state tuition."

They are not legal residents. They should not be recieving in-state tuition. Illegals are catered to on many levels and feel they can get away with anything. The more you give, the more they want. They will stop at nothing but full amnesty for them and their entire families.
