And maybe Mr. Garung was initially released so the dim bulb could be followed and lead the FBI to other terrorists.
And maybe Mr. Garung was only charged with a misdemeanor so he could be released so he could be followed so he would lead to other terrorists. (Surely by now it's more than a misdemeanor to carry 9 lockblade knives, mace and a stun gun in an airport terminal!)
(..sigh..) It's not making much sense, is it? I just know that my own local FBI agents have a good reputation and I have confidence in their detective abilities, so it's hard to imagine a city like Chicago would have agents who don't know what they're doing.
And no! You can't have them!
