Interesting point about names. I wonder if people with middle-eastern names are going to or thing of changing them to something less revealing and more American sounding? Like, for instance, Jews and other immigrants did earlier in the last century?
Michael McDermott’s online chat habits (he hung out in an explosives chat) were reported in the media and possibly used by the prosecution in his trial, certainly sundry computer records were (he researched how to fake insanity, and apparently didn’t bother to get rid of the information he’d collected before trying an insanity plea.) But you know, they didn’t bother him about any of that until after he shot 7 people. Now I just spent ten minutes googling McDermott, which shows an unhealthy interest in mass killings, so I guess if googling can be bad for you, I’m in trouble!
My gut feeling is that they’d either need to be looking at users of specific websites you hit for some reason, or looking at you for some other reason, for your websurfing habits to be of interest to law enforcement agencies.
I was participating in a debate here a few months ago in which I needed some info on the first WTC bombing. So, I typed “Bomb World Trade Towers” into google to get the info I needed. Afterwards, I thought: Man, if the feds really are watching, I just did something really stupid. 
Googling is nowhere near as dangerous as Graham’s Numbering…
In terms of law and if googling for bomb-making ingredients are applicable in court: I would think that they would be just as applicable as if there is a record of the guy going to a demolitions expert. The problem is that it would be a pain to find that record, and then substantiate it in a court of law. While in my analogy, there would most likely be a video or something tangible, all we’d have in the googling case would be the history in the browser. IANAL, but I don’t think that it would hold up in court.
As far as whether it is a good idea: It’s free speech, what can you do? I know that I have looked at the anarchist’s cookbook in the past, but only for reasons of curiosity. Are there people who will use it for bad? Yes. Are they gonna get the instructions anyway, whether or not they can find them online? Probably. Can we get rid of all of the instructions anywhere without going to full on fascism, government in control of everything? No.
However, there is an inherent flaw in my above argument. It assumes that the person has intent to commit the crime and goes online searching for these instructions. But, does making these instructions available online make people more likely to commit these crimes? I don’t know, quite frankly. Does anyone?
Too true, Tris. The right of one American should be the right of ALL Americans, regardless of race, creed, political affiliation or hair color. Too often, recently, it seems that the rights of the wealthy and powerful are in a whole different class than the rights of the common citizen. I suppose it’s “human nature” … but it’s still disheartening.
I had some paranoid thoughts on the subject of web searching quite some time ago, and I spent a lot of time meditating on it. Eventually I came to this conclusion: I am just about as law-abiding a citizen as it is humanly possible to be, in this nation of too many laws. If some Great Unknown wants to come after me, I’m sure s/he can come up with something more incriminating than the search I did last night for “Glowing Fish Heads.” If they want me, they can get me, no matter how straight a line I walk. So I don’t think my Googling habits are worth worrying about.
Anybody else here flashing on George Carlin’s routine on mortal sins?
Hm, $200-300US electric bills. They would have a cow at some of my $400-600US electric bills=\ Grow lights my aunt fanny. Try heating a workroom in a barn with electric heat because you need to be out working on a project in the winter, and then running an electric kiln for the better part of a week=)
