At least I didn't accuse her of bombing the train station 
The hotel rep, gave me some advice, and it scares the shit out of them, as it draws attention to them, and the Poliza are likely to come running, to the shouting
Learn some Italian words, or what every country your in, learn a certain phrase
raccogliere la tasca which means pick pocket, pronounce like
le coil ya la taska
Something like this is effective, and I have sen it put to use, last week flying home from Venice airport, when all I hear is shouting, and find out, it was pick pocket, and he had been caught, and the person he tried to pick his pocket, shouted as loud as he could
The pick pocket is well aware the army and the police are in the area, so he ran as fast a he could, but was soon caught
