IRAQ THE MODEL

In an attempt to protect their city from suicide car bombers, the local authorities in Tikrit set an emergency rule for driving on the streets; the new rule says that "no drivers will be allowed to drive their vehicles alone, i.e. every vehicle has to carry at least two people to be allowed to move on the streets".

The local police said that they will shoot at any vehicle that violates this rule and I heard that such an incident did happen once at least in the last few days.

I don't know how practical this is or how effective it is going to be and of course it's going to have some undesirable economic side effects as it's going to severely restrict the movement of Taxis and lorries but if it's going to save one life then it's certainly worth it.
