A request. -- old thread?

No: HPFGUIDX 146566

I was wondering if there are any semi-old timers that could direct 
me to the thread that made a splendid case for the Dumbledore 
kills Sirius in book 5.

I would really appreciate it as I would love to look over its well 
thought out analysis and compare it to what we now know with book 
6.

Anyone have this logged under a favorites? Or what number this 
might be?

Thanks in advance!
