There is so much crap out there that can kill you. You will never be safe. You can never be certain that those trying to protect you can protect you. Videos like this serve no purpose. Do you think you are more safe now that you know about binary explosives? You are no less safe either. There really isn't a point in living your life afraid all the time. If I die, well, I know what lies ahead.
I guess that attitude that a healthy religious life can give you helps you through these types of issues.
