On another note... a sick and devious mind is going to employ tactics like making gasoline bombs, homemade grenades, and generally any other IED device. All it takes is a little time, a place to experiment with the chemicals, and maybe MINOR technical knowledge. I mean how many people are certified electricians, and how many of us can go online and find out about simple electrical devices? Hell you could go to the public library if you wanted too. I am sure if (and when) any redneck put their mind to it...they could come up with explosives that could kill dozens.
