Annie Jacobsen, who has been writing a series on "Terror in the Skies" after her experience on a flight this summer that had young Arabic males performing what many passengers believed to be a "probing" flight. In this last episode, on the 2nd page she discusses FAM ammo choice of .357 HP http://www.womenswallstreet.com/WWS/article_landing.aspx?titleid=76&articleid=776 quote in part: < Are FAMS Using 'Cop-Killer Bullets?' News reports on the FAMS ballistics have, so far, been extremely limited. Early this summer, the FAMS had granted an exclusive interview again to TIME Magazine writer Sally B. Donnelly. In Donnelly's article, 'My Life As An Air Cop,' she states she was the first journalist ever allowed to drill alongside [FAMS] recruits. In the article, Donnelly revealed that FAMS use hollow point bullets designed to mushroom inside the human body. Why the FAMS wanted to release these gruesome ammunition details to the general public, I really don't know. But what I do know is that according to my anonymous sources, the facts presented by Donnelly are not entirely true. Hollow point bullets may be designed to mushroom inside the human body, but if they're the kind of hollow point bullets the FAMS uses -- SIG-357-HP's according to my sources -- then they travel about three times faster than other bullets. Couple this with the incredibly close quarters on an airplane, and you've got a problem. When fired at close range, the bullets used by the FAMS will likely travel not just through the targeted assailant, but also through up to four more bodies -- and possibly through the cabin wall of an aircraft. Apparently, I'm not the only person with this conflicting information. Here's how Congress posed their ballistics question to Quinn: Contradictory reports of the type of ammunition used by air marshals has sparked concern by travelers, pilots and others. The debate includes whether all passenger aircraft can withstand impact by the type of ammunition used by air marshals and whether the ammunition is the type that continues to travel through the human body. Please provide examples that clarify the impact assessments for each type of ammunition used including, but not limited to, the effect on an aircraft and a human body from being penetrated by the ammunition used by air marshals when fired at varying distances. Equally disturbing, it's been suggested by multiple sources that the FAMS use these high velocity, hollow point bullets not because they're the appropriate ammunition for the job, but because Secret Service uses these bullets and that's where Director Quinn spent 20 years of his career.> end qoute My purpose in this thread is not so much to point out journalistic misinformation, but rather clarify what we do know about this topic from the collective firearms knowledge at High Road. Then, I will point her in the direction of this discussion to further educate her. I think this is worth the effort since this series she has been writing has taken on a life of its own and has a huge following - a following who should have accurate info on ammo (aka 'cop killer bullets') My first question - I thought frangible ammo was being used. ??
