What if someone borrows few thousand dollars from a friend, and after few weeks the friend who lent the money is in serious need of that money. You obviously have to return it.

State attorney may think is it possible that similar types of transactions (borrowing/returing back) were happenning among a considerable number of people at around the same time.

But, everyone can claim ' i dont know what other people did, but i had to return the money as my lender was in serious need.  And, i did not know that i should have reported the change in account balance to the immigration office."

I dont think they will get a 10 yr in prison or $250,000.
