You should be worried that even the police are so darn stupid that they do not understand that bombs are things made out of EXPLOSIVE MATERIAL, and not boxes with wires like you see in the movies. EXPLOSIVE MATERIALS are dangerous. So are the triggers that set them off because they are small containers of explosive that can be set off by an electric current.<p>Switches, on the other hand, are not dangerous unless they are attached to a blasting cap and other EXPLOSIVE MATERIAL. Neither are mobile phones (even though ALL MOBILE PHONE BATTERIES ARE MADE OF EXPLOSIVE MATERIAL) and neither are timing devices such as clocks. A clock is not even dangerous when it is attached to a switch, unless of course, a blasting cap and EXPLOSIVE MATERIAL is already attached.<p>Police and other personnel responsible for public safety, like teachers, cannot be allowed to wallow in ignorance living in a fantasy world. They must have some awareness of REAL THINGS so that they can recognize dangers. Why are these people not trained how to recognize EXPLOSIVE MATERIALS, triggers, blasting caps, etc.?<p>There are enough crazies out there know, also living in a fantasy world, that the people charged with public safety need to know how to distinguish REAL THREATS from Hollywood fantasy. I blame the incompetence and corruption of management, i.e. school boards, police commissioners, mayors, etc.
