He couldn't wait to snuff the one guy who could connect the Iraqis to OKC....Tim McVeigh!Someone else HAS connected the Iraqis to OKC, so Timmy was obviously not the only guy who could do so. And Timmy wasn't going to rat anyone out--he viewed himself as some sort of brave, glorious warrior.
Timmy died pre-09/11. Would he have eventually confirmed details discovered elsewhere? Whould have have had a change of heart and talked? We'll never know. But if it might save one future life, I sure wish we had that option.
