I am writing with regard to the report "Haia car chase: Both brothers are now dead" (Oct. 2). I have never understood why the Haia have to chase people. I have read a lot of articles which report such chases and that they often lead to very tragic accidents. Who is right and who is to be blamed for this? I believe that the members of the Haia are well-versed in Islamic rulings and teaching. So, why does this still happen? HaNaj, Online response II.

Is this the first time he has seen this? KMA, Online response
