Own goal - accidental or deliberate?

[Ian]

accidental vs deliberate and how to define

- I sort of wish I hadn't mentioned the ridiculous 'end switch' game that occurred -
I was hoping that with all the ref'ing power out there, someone might be able to assist with an interpretation of what constitutes:
'deliberate'- hence violation and no score and
'accidental'- hence score stands
Any thoughts? or does anyone know of official FIBA interpretation that covers it?
btw - FIBA replied to my question but to discuss it, they want me to ring headquarters (in Germany?)
