Hmmmmm, new twist on using the womb as a WMD.
Especially when you think about the wombs that produced UBL, Zarcreepy, and all of the other screaning mad jihadists.
In some ways a semtex, ahem, "diapraghm" will only kill within a certain radius, while giving birth to these aforementioned monsters has killed thousands worldwide.
perhaps developing an explosive-sensing device that also sterilizes would help?
