Hypothetical situation

[stevenstat]

The "accidental throw", I believe, is to cover a situation where a player goes to pass or shoot and the stick flies out of his hands - he provided the momentum, even though accidentally. This player did NOT "throw" his crosse. He was clearly trying to deke and got hit and it flew out of his hands.

He did not participate without his crosse. He just stood there after he lost his crosse, and a second later the crosse and ball were in the goal, which ends the play whether or not you award the goal.

The slow-whistle technique is employed, but there is clearly no flag down, and in any case, the play does not end (whistle blow) until the ball hits the ground inside the crease.

The crosse made no contact with the goaltender and is now in the goal, not in the crease, so it did not interfere with the goaltender.

So I don't think any of these precisely applies, but I will agree it requires a tortuous parsing of the rulebook.
