I am not allowed to have privacy on telephones or electronic communication. Several government agencies have started programs that eavesdrop on citizens, sometimes at random, looking for "terrorist intelligence". Police are no longer required to obtain warrants to tap phone/internet lines. Any intelligence gathered can be used against me for any reason, not just terrorist-related charges.
Correct me if I'm wrong on this, but I believe the government has been taping telephone conversations with automated computers since the dawn on the computer chip. Whether they put more money into the program, and now actually have a chance at listening to you specifically, I don't know. Computers were auto recording specific words over the telephone long before 9/11.
I am not technically allowed to have a container of household bleach under my kitchen sink. Such items are "chemical weapons of mass destruction". Of course, they're obviously not such weapons, but under the definition of "chemical weapons of mass destruction", most household chemicals could result in federal terrorism charges. That the government has not persued such a case does not matter, they could do so with no hinderances.
I think, unless my study of law and history proves wrong, that you aren't allowed to "make" anything with your household chemicals. I think the law you are referring to came about long before 9/11 to deal with bomb makers. It is also an often misunderstood law. You are allowed to go to a garden supply store and purchase legal chemicals, but as soon as they are mixed they become illegal.
Bleach is not illegal. Bleach along with other chemicals, mixed with the intention to due ill, *IS* illegal.
