Aliens vs illegal immigrants

The tone of the discussion has been set by the choice of terms.  By casting aliens in the United States as “illegal immigrants” it gives the imprint of immigrants to someone in the United States who is breaking the law.  It is like calling an armed robber, an illegal customer.

If we are going to decide that only some laws have to be uniformly applied, can we pick and choose which laws we have to obey?  I thought not.
