Query: 60"s Radical - WOW!

I'm not sure why I bought this book. I guess I thought that it would be cool to be able to recognize booby traps or learn how to defend your home and family if the collapse of civilization as we know it really would happen. I was wrong! The author (who's probably passed on by now) is a real sicko! I'm certain that this was written for 60's radicals in confrontations with the authorities. This book is dangerous in the wrong hands. The only good feeling I got from it was that since 9-11, most of the easy to get chemicals listed aren't so easy to get anymore. And the people who sell them are more leary about the people who try and buy them, at least I sure hope they are!I wouldn't waste my money.
