Prosecutor says Pistorius acted methodically

PRETORIA, South Africa (AP) — Oscar Pistorius armed himself and took other methodical steps before he killed his girlfriend, the chief prosecutor said Thursday, trying to cast doubt on the athlete’s account that he reacted instinctively to a perceived intruder.

Prosecutor Gerrie Nel made the argument while cross-examining sports physician Wayne Derman, who testified that the Paralympian acted on a “fight or flight” impulse in which he chose to confront what he thought was an attacker because his disability prevented him from fleeing. Derman has treated Pistorius for years.
