Sinn Féin leader Gerry Adams has been arrested for questioning about the 1972 abduction and murder of Jean McConville, a widow wrongly suspected of informing against the Irish Republican Army.

Adams was implicated by two IRA veterans who gave taped interviews to researchers for a Boston College oral history project on the four-decade Northern Ireland conflict known as the Troubles. The tapes were made available to Northern Ireland/British police in a complicated court battle. Here’s some perspective from a B.U. trustee.

Adams made himself available to the authorities, but denies any role in the killing. Here’s his statement on the Sinn Féin website.

Obviously, this story is developing. We will have to see if Adams is charged, and what impact this might have on upcoming elections and the ongoing peace process in Northern Ireland. No doubt many on the island of Ireland would like to see Adams removed from politics and the public stage. But he has his supporters, as well, and has demonstrated an amazing talent for survival over the decades.
