Palestinian ambassador in Prague killed in blast

[Igel]

4. On a hunch ...

It was rigged 20 years ago by somebody who knew what needed to be done if the safe was improperly opened. An old PLO safe, therefore not "safe" by most standards.

If the wrong person opened it--a safe-cracker, or somebody who stole the combination--then they'd be hurt bad. Thus either protecting a secret or just nailing somebody opening safes at random.

That person didn't leave instructions behind. Probably forgot about it. Might be long dead.

So it was intentionally booby trapped. But the booby who opened it wasn't the intended target.
