Not that I want to discuss about manners but, after someone told you, unrequested, some very personal stuff, I don't find it impolite to ask some further detail- although I accept it if he doesn't want to answer. The question in itself wasn't out of idle curiosity but because the sentencing seems disproportionate. I wanted to double check this before launching in a tirade against the US justice :)
