"Norway Gunman Fired For 1.5 Hours On Island"

Well, I guess that this article explains why so many people were killed. Unfortunately, no one was around for 1.5 hours with a gun to stop this. From Fox News:

A gunman who opened fire on an island teeming with young people kept shooting for 1.5 hours before surrendering to a SWAT team, which arrived 40 minutes after they were called, police said Saturday.
Survivors of the shooting spree have described hiding and fleeing into the water to escape the gunman, but a police briefing Saturday detailed for the first time how long the terror lasted -- and how long victims waited for help.
When the SWAT team arrived, the gunman, who had two firearms, surrendered, said Police Chief Sveinung Sponheim.
"There were problems with transport to Utoya" island, where the youth-wing of Norway's Labor Party was holding a retreat, Sponheim said. "It was difficult to get a hold of boats, but that problem was solved when the SWAT team arrived."
At least 85 people were killed on the island, but police said four or five people were still missing. Divers have been searching the waters around the island. . . .

Google Maps indicates that the distance from the shore to this island is less than 2,000 feet, less than 4 tenths of a mile. From the Associated Press:

Police arrived at an island massacre about an hour and a half after a gunman first opened fire, slowed because they didn't have quick access to a helicopter and then couldn't find a boat to make their way to the scene just several hundred yards (meters) offshore. The assailant surrendered when police finally reached him, but 82 people died before that.
Survivors of the shooting spree have described hiding and fleeing into the water to escape the gunman, but a police briefing Saturday detailed for the first time how long the terror lasted — and how long victims waited for help. . . .
A SWAT team was dispatched to the island more than 50 minutes after people vacationing at a campground said they heard shooting across the lake, according to Police Chief Sveinung Sponheim. The drive to the lake took about 20 minutes, and once there, the team took another 20 minutes to find a boat.
Footage filmed from a helicopter that showed the gunman firing into the water added to the impression that police were slow to the scene. They chose to drive, Sponheim said, because their helicopter wasn't on standby.
"There were problems with transport to Utoya," where the youth-wing of Norway's left-leaning Labor Party was holding a retreat, Sponheim said. "It was difficult to get a hold of boats." . . .

So why couldn't they have sent over four or five people at a time go over to the island? Reuters has this story here:

The near-sinking of a police boat and a decision to await a specially armed unit from Oslo some 45 km (28 miles) away delayed the Norwegian police response to an island where a gunman killed 86 people.
"When so many people and equipment were put into it, the boat started to take on water, so that the motor stopped," said Erik Berga, police operations chief in northern Buskerud County.
"The boat was way too small and way too poor," he said, referring to a police vessel that had been transported to the scene from nearby Hoenefoss for crossing to Utoeya island. . . .

Apparently the attack was planned for two years in advance.
