Scoreless at the half

Why is Japan kicking free kicks in the box instead of on goal (where they scored twice last match)?  Nice to see FIFA's Shep Blatter admit two mistakes by the refs (MEX, ENG) but what about USA's???  Goal line technology is necessary because the linesmen and ref are never going to be in the best position to make that call.  That blown offsides call was just that... a blown call by the ref.
