Several people commented that something to the effect "...no matter what you come up with there will be people who thought it up and wrote about it before you did..."
I do not dispute that.
But to write a realistic piece of fiction I need to research the topic and that throws out a multitude of scent trails that look like "evidence of intent".
It is my impression that the FBI is very, very weak on boots-on-the-ground investigation but extremely diligent for cyber footprints.
Yes, I know there are all kinds of "anonymizers" but that looks like evidence to a prosecutor building a case.
Consider the research that goes into one attack scene. Let's say the bad-guys want to take out a set of power transformers because they take longer to replace than transmission lines.
I would have to find a substation with transformers that would be "interesting". And as much as the residents love Brandon, South Dakota it would not have the same dramatic impact as a substation 20 miles from Foggy Bottom.
Then I would have to research the guts of large transformers to determine the axis of attack that was most likely to produce catastrophic, cannot-rebuild damage.
Then I would have to research drones, limpet mines, Tannerite and shaped charges.
Even if I detuned the information to make it less useable, I would still be leaving footprints all over the internet and move my name up that list that everybody is on.
Every person has one book in them but very few have two books worth writing.
I have been lucky.
It would be boring to write the same book over, and over, and over again.
Some authors churn out hundreds of books. They change Barbara-> to-> Brenda, Brant-> to-> Brent, Architect-> to-> Geologist, Seattle-> to-> Tacoma, Stucco-> to-> clapboard, Chestnut St-> to-> Walnut St. I swear they must have an Excel spreadsheet with pull-down menus of popular women's names, guy names and so on. It works for them but it will not work for me.
I ENJOY the act of digging into new things and the pain of trying to wrap my mind around them.
And I don't have the time right now. It feels like we are in a lull and I am busy battening down the hatches and inventorying items I might need in a hurry.
