There is a detonator or pull switch or microswitch in there. and the other thing is that some things to look at. we can t confuse the bomber s intent with his ability, as jonathan pointed out, it could have been poorly made. ki look at it and te and i ca the tell you many of the things that are poorly made, and i don t want to educate the guy, so i won t point them out, but every person was opened by a civilian target, and the bomb squad opened, so we don t know how it would have happened in a civilian s hands, and we don t know that yet. they are looking at that in the lab. and secondly, shrap nenel is ine of it. and many times they will ut strap the nails on the outside so it is looking scary.
On the heels of that would be a message from the bomber, and that message would be on the similar typing on the outside of the envelope as has been exhibited on the cnn photos, and it would have said see, i could have killed you, the next ones will be real. so if they are fake devices or with real explosive components i would expect a message. so we ll see. maybe not, but that s how i d be looking at it as a commander of a bomb investigation. now he wants to say why did he do it this way? if in fact were real devices and none of the packages were opened by law enforcement who knows how to open a package like this who knows how to detonate it, it could be live devices by friction, a pull switch, a tripwire, a light switch when it sees the light. any kind of switch, mercury switch. all keends inds of ways it can designed with delays and funks,
