TOKYO (AFP, REUTERS) – The head of Japan’s National Police Agency announced his resignation on Thursday (Aug 25), taking responsibility for the shooting of former prime minister Shinzo Abe in July.

“We have decided to shake up our personnel and start afresh with our security duties, and that’s why I tendered my resignation to the National Public Safety Commission today,” Mr Itaru Nakamura told reporters.

He made the announcement at a news conference detailing the findings of an investigation into flaws in how the former prime minister was protected.

“As we scrutinised and reflected on the incident, we decided to start over and overhaul our security system… To mark our fresh start with a new security plan, it is only natural for us to build a new organisation,” said Mr Nakamura. 

Mr Abe was shot and killed on the campaign trail on July 8 in the western city of Nara.  His suspected killer was detained at the scene and is believed to have targeted Mr Abe because he thought he was linked to the Unification Church. 

Mr Abe was Japan’s best-known politician and longest-serving prime minister, but security was comparatively light as he delivered a stump speech on a street in Nara.

Local police in the area have already acknowledged “undeniable” flaws in security for Mr Abe.

The resignation by Mr Nakamura, whose agency is in charge of Japan’s police, represent the highest profile fallout from Mr Abe’s assassination.

Security in Nara on July 8 had been widely seen as insufficient.

Bodyguards could have saved Mr Abe by shielding him or pulled him from the line of fire in the 2½ seconds between a missed first shot and the second fatal round of gunfire, eight security experts who reviewed the footage have told Reuters.

The chief of the Nara police also announced his intention to resign, Japanese media said.

Japanese officials, including Prime Minister Fumio Kishida, have acknowledged flaws in the security around Mr Abe’s appearance at the election campaign event.
