RULING: B1 is charged with basket interference and a two-point goal is scored. Team B is awarded the ball for a throw-in anywhere along the end lines as after a scored goal except the official shall place the ball at the disposal of a player of Team B for a throw-in from any point outside the end line.

Ok, fine, I admit it, I did not realize that BI does not specify a try, I would've messed this one up. That said, why in the hell do the rules allow this to happen???? Is this simply an oversight that has never been changed/addressed, or is there a purpose for this ruling?
