I am only as far as your post, but as I read along, I keep wondering about the timeline for this.
Has one come out yet? If he was seen in Oslo at the time of the bombing (one report suggested that?), how did he get to the island. It didn’t look that close on the map, and if it was 20 miles off the coast ~ boats/ferries don’t go all that fast!
Something seems off about the timing.
Google maps estimates 36-48 minutes to drive just to the ferry from Oslo. So from the map, it looks like it’s just over 1000 feet off the coast. The ferry couldn’t have been more than 5 or 10 minutes.
That gives him anywhere from 40-60 minutes from the time the bombs went off. Theoretically, plenty of time for him to do this all himself, but I have read an article that states that there was shooting coming from two separate places on the island at the exact same time. It appears that Breivik had an accomplice. I wonder if this person could be among those that had been at the camp as campers and was then evacuated out as a victim.
