Hmmmmm that theory does sound plausable. the only thing i don't understand is how harry got out alive.
actually come to think about it there are many things about this whole incident i don't understand!
1. the attack happened at night
2. sirius rushed to the house but was too late
3. hagrid met him there and borrowed his motorcycle to take harry away
4. all the next day wizards were celebrating the downfall of LV
5. hagrid arrive at 4 privet drive that night and dropped off harry, then left to return the bike to sirius.
now do you honestly believe the trip took 24 hours from godrics hallow to privet drive?! and why would sirius wait 2 days for his bike to return. it would only make sense if sirius and hagrid met at the house 24 hours after the attack. but then that doesn't make sense because...
1. how could harry survive the destruction of the house and then waiting in the rubble for a whole day
2. if every wizard knew what happened why didn't anyone collect harry earlier?
3. if peter was there why didn't he do anything about harry?
and there's one last thing thats always bugged me... at the very start of PS when mcgonagall is talking to DD se says

you think it - wise - to trust Hagrid with something as important as this?
what exactly is SOOOOO important about transporting a baby that she sits and waits all day rather than celebrating the death of the most evil wizard of all time? did she know about the prophecy too?
