Craziest ending of a game ever?

[ref4life]

Long process hear but read it all its crazy, saw this game the other night in a district final to make it to state. Team A is up 1 at the line shooting a 1 and 1 with 15 seconds left. Misses the front end Team B comes down throws up a three and drills it with 6.5 left. Team A calls timeout sets up a play, they come down throw up a 30 footer and airball it with .1 seconds left. Team B's bench players storm the court along with their crowd. Refs get together and discuss the situation. Decide that Team B is issued with a Technical Foul and Team A gets two free throws, the Technical was for the bench of Team B coming onto the court. Team A makes both free throws to tie the game and take it into overtime and end up winning. Pretty crappy way to lose your last game. Thoughts on ruling?
