The conspiracy theorist in me suggests that there will be a report from this incident suggesting that current security measures are inadequate and they will have to be ramped up.
Who was it that had the Taser how did he get it past security and how did it magically fall out of the bag at the wrong time? I will bet folding money anyone who has a taser legally will know they are not to be put on a aircraft and anyone who is carrying one illegally would not let it fall out of a bag.
Interesting to note that the Feds have circled the wagons on this one.
