The credibility issue at hand is not even so much that these documents seemingly arise from vaporous origin -- no glimpse provided of the labors or mechanics at work (that would help, BTW) -- but that these two could be mistaken for what they portray themselves as.
Neither has the requisite age, bearing, demeanor, lingo or plain gravitas to pull any of this off without great, intense and ultimately, one would think, insurmountable scrutiny by officials of the Government such as FBI no less. That they could saunter unchallenged and unescorted into some heavily guarded hanger because they donned black suits and presented some Johnny Ranger token badge at a distance...? And they were supposed to be Homeland Security? -- sans appointment notification?, absent a confirmation email at least?
Oh, I sure hope the security protocols are much better than that! -- but I return to their appearance -- I'd take one look at these juveniles and really wonder what the heck is going on in the Government that THEY should be the appointed representatives or spearhead field agents -- I'd give that badge a good going over, then call every level of authority I knew to avert compromising my position on a horrendous misstep of the caliber it would be to accept these two as anything other than delinquents. OK, now if the conceit is that they are just so hunky that pretty chicks along the way are going to overlook the obvious and buy into what their selling, so be it, just not anyone else, please.
