Free Throw administered incorrectly

[frezer11]

*Fair warning, the first paragraph is some backstory about the event, but is not necessary to answer the question. Skip to 2nd paragraph for just the situation: Boys varsity game, a competitive game with really no issues between players and coaches. Early 2nd quarter, A1 has a breakaway layup and is fouled from behind by B1. The foul is legitimate, never considered intentional for a second, but B1 while trying to block the shot came over the top of A1, and their arms get tangled, with neither letting go. A couple shouts and shoves and we have a double technical foul. Pretty standard, no issues there. A1 is immediately restrained by his teammates and cools down quickly. B1 however, walks toward his bench while staring down A1. Arguably another tech there, but while walking he then sees A2 in his path, and intentionally chest bumps him, and A2 responds by shoving back. So we have another double T, which gives B1 his 2nd. Some confusion occurs in reporting the fouls, and the official administering FTs thinks the sequence went 1) shooting foul, 2) double T, ) single T, and administers the shooting foul shots with no one on the lanes. After the 2nd shot, the crew realizes that there are no further FTs to be shot, and that the lanes should have been occupied.

So the question is this: If you have a shooting foul followed by off-setting Techs, you resume play by shooting the FT for the shooting foul with lanes occupied, as if the T's never happened. But if the officials err and shoot the shots with the lanes cleared, now what? Go to the possession arrow? Does it matter if the 2nd FT is made or missed?
