OSLO, Norway (AP) - Anders Behring Breivik knew it would take practice to be able to slaughter dozens of people before being shot by police.
In a chilling summary, the far-right fanatic claimed Thursday that he sharpened his aim by playing computer games for more than a year before Norway's worst peacetime massacre.
Breivik told an Oslo court he took steroids to build physical strength and meditated to "de-emotionalize" himself before the bombing and shooting rampage that left 77 people dead.
His lack of remorse and matter-of-fact description of weapons and tactics - he even considered using a flame thrower - was deeply disturbing to families of the victims, most of whom were teenagers.
"They perceive him as evil and dangerous and reopening wounds," said Mette Yvonne Larsen, a lawyer representing the bereaved. Some of them are following the proceedings in court; others are watching it by live video link in more than a dozen courtrooms around Norway.
"It's one thing to read explanations, it's not the same to hear a person present such a message," Larsen said. "I am personally quite shocked."
Pictures of the confessed mass killer, smirking or flashing his clenched-fist salute, clutter newspaper front pages. For those who have had enough of his antics, newspaper Dagbladet's web site allows users to click a button to read a Breivik-free edition.
