been a good lead yet? >> no this happens all the time. the more important or significant the case is, the nor happens. other case where a huge reward is aired, same thing. in this case, the reward would be fame, if the area of one that provides the lead that solves the case. but fwhau does lead to millions of pieces of information that come in that have to be gone through and in some case, you know, investigators reforethat as drinking through fire hose, that you're just getting too much to deal with too soon and it's very difficult to sift through that and narrow it down. >> joe, as you point out, all these leads, they do really overwhelming investigators, too, if they check out everything. >> it's very true. in the sniper case, 100,000 or more leads, just a traction of those were anything substantive at all the other thing i think is true, and we know in our own business, information self-correct. so you get a certain piece of information, maybe it's not quite right, the more time you massage it, try to figure it out, you will get to the kernel of the truth it takes a long time.
