I have no agenda, I'm no law maker, whatever I think or feel will make no impact on the laws this country makes. I could think putting evil purple monkeys into classrooms and it wouldn't effect any laws.
As for sky marshals like I said they have no effect on hijackers now in a post 9/11 America, the purpose they serve now is the peace of mind to the people flying in the planes, it makes people flying in the planes in a post 9/11 America feel safer knowing that there are undercover officers on planes with guns. Honestly do you think that sky marshals are whats preventing Al Qaeda' & other terrorist from trying to hijack another U.S airliner? I know I don't think thats what it is, IMO it's the increased security now to get on a plane, now-a-days you can't even get a finger nail clipper onto a plane. The other thing preventing Al Qaeda' & other terrorist as I've already stated, the people on board that plane would never allow it to happen, they would rush the hijackers and stop them.
As I've said, yes before 9/11 sky marshals probably did have an effect on the minds of potential hijackers, but not anymore, now there are other things preventing them from trying it.
