I’m assuming that the Rumanians to whom the writer was referring are the Gypsies. The “Romany” have been the criminal class in Italy for as long as I can remember.
Ah, the joys of multiculturalism!
The Roma to which you refer may or may not be a factor of the Romanian immigrants mentioned. The Roma make up only 3.2% or the Romanian population and are Indian ancestry, not Romanian (as the name purely coincidentally implies).
