Diplomat arrested for paying Nanny $3. an hour

Is this overkill? A US employer was taken away in handcuffs at her child’s school for paying her nanny $3.31 an hour.
On the surface the reaction from authorities seems excessive. This employer is a diplomat who is “know for championing women’s rights” This is obviously unacceptable behavior especially as she apparently encouraged her nanny to falsify visa documents. I have met many nannies who have been underpaid but this is truly the ultimate irony. Check out the Globe and Mail article
