Seat belts

This morning a cop stopped me for not using the seat belt while driving. He asked me where my belt was, I showed him where it was. Then he said ,"I can sue you for violating traffic rules." I replied that this particular rule would be applicable from November 1, 2010, as has been mentioned in the media.
I wrote on this topic earlier, wherein I mentioned the seat belt was the cause of death of late Mr. Saifur Rahman, as has been revealed. Seat belts are meant to save lives.
It is applicable for America and Europe, where people drive at high speeds. There are no or very few examples of death occurring from car crashes for not using seat belts in Bangladesh.
I wonder whether the concerned lawmaker or the police are aware of this or not.
