Perhaps even more alarming are the stabbings that took place in Surrey, as a sign of a society in civic decline.
Here in Paris, several days back, the carrriage of a southerly rapid rail commuter RER was overtaken systematically by a group of teens and pre-teens, 12 to 15 years old. They sprayed tear gas in people's faces and robbed them, and then fled.
Four were arrested.
On the Yahoo site on which it appeared there was a special request not to leave any comment or feedback due to the "delicate" nature of the incident.
