What would you have done?

[Mark Padgett]

Middle school classic level boys tournament this past weekend. On Sunday, I was sitting behind scorer during 7th grade championship game waiting to do the 8th grade game. Both officials are about 5 year veterans. With about 20 seconds to go, game is tied. A1 to inbound in frontcourt on side near division line. A1's pass hits A2 on hand in frontcourt, caroms into backcourt where A2 recovers. Trail calls over and back violation.

Neither coach says anything and lead is also quiet. B1 inbounds and B2 hits jumper to win game.

My question is: should I have stepped in and said anything when it happened? What would you have done?
