you see it all the time in news clips
bad guy goes in to rob the convience store, the cash register is empty... they go bullistic because there is no money and start breaking things and sometimes hurting themselves, some even sue the store owners
Your analogy is really bad. The illegals are not using guns, they are not thieves, they have not gone ballistic, and if anyone is the thief, it is the guy who promises to pay and then does not pay.
