U.S bombs civilians again!

This is not anything new.the united states has bombed inocent civilians all over again.when will this end?what i fail to understand that with all the high end technology they still get it wrong and kill innocent people all over again.this time it was in afghanistan!
fraknly i have to say that such shoddy behaviour on the part of the soldiers is unforgivable.granted that they are fighting a dirty war out there but nothing,nothing can excuse the killing of innocent civilians!
