Sunglasses Technical Foul

[kstiles99]

So I need some insight on this situation..
Middle School girls scrimmage, late in the game with two teams tied...
B1 has the ball near her arc when A1 bumps her with her hip. I call the block. When i reported the foul, Team A's assistant coach jumps out of seat going beserck, because he felt the foul should go on A2 instead of A1. The guy had his sunglasses resting on his forehead (I guess because he forgot to take them off when he came in) and spins around and chunks them at the empty practice court adjacent to the main court. They shatter into several pieces. I call a T on this, and he slowly calms down as I speak to the head coach about this. Was the situation handled right? Was the T warranted? What would you have done?
