Using renewable or nuclear power, one could easily build Sabatier reactors to make methane from atmospheric carbon dioxide and water, and then just pump it into old natural gas wells and other suitable geological formations. From there, more complex hydrocarbons can be made. Far easier to do this and make carbon-neutral and energy-dense fuels than to try and keep hydrogen from escaping (the main issue with storing large quantities of it).

>They all use common slightly hardened microcontrollers

No, not all of them - there are several that use the combination of a microcontroller for UI / communication and a real secure element for securing the cryptographic keys (e.g. Ledger's Nano S uses ST31 and the Nano X uses the ST33). Also, while the NSA might have the ability to break into these, they probably aren't going to share it with the IRS or other alphabet agencies unless there's a real national security issue at stake, since extracting data from a secure element is usually a non-trivial amount of work even for a government agency.

Tanks typically have a "Commander" position to go along with the gunner, driver, loader(s) (for tanks without an autoloader).

No, you've got two situations (being called in front of a grand jury and being tried in a court for a crime) mixed up. If you are called in front of a grand jury for questioning, they aren't going to have people testifying against you. And, if you are accused of a crime and are brought to trial, your lawyer should be cross-examining the witnesses and attacking their credibility or otherwise asserting your claims of innocence.

You can run airplanes on biodiesel or alcohol if necessary.

Weak on terror? He personally ordered the assasination of Osama bin Laden; I don't think anyone could accuse him of being 'weak on terror' and keep a straight face after that.

And all of that capability means nothing if the people using it aren't willing to cause enormous civilian casualties, because people aren't idiots and aren't just going to line up on a field for the army to shoot at. All the conventional firepower in the world isn't going to matter when it comes to guerrilla warfare, as we've seen in Iraq, Afghanistan and Vietnam.

There's always option 4, finding a small airline or pilot for hire to fly you to where you want to go. Admittedly not the cheapest option, but you get the convenience of air travel without having to deal with the TSA. These guys, for instance, would be perfect: http://en.wikipedia.org/wiki/SeaPort_Airlines

I'd take a page out of one of Bruce Sterling's short stories and go back to harvest the past's resources to sell in the future. Also maybe bring back some famous people. http://www.docstoc.com/docs/19893228/MOZART-IN-MIRRORSHADES-Bruce-Ste

The acoustic dead-man's switch wouldn't have been any help, since it's linked to the same valve on the BOP that failed even when they sent robots to manually shut it down. And, that valve failed because of an accident that happened some weeks before that destroyed the annulus seals: http://www.cbsnews.com/stories/2010/05/16/60minutes/main6490197_page4.shtml. I agree that the relief wells should be required for this kind of eventuality, but if BP hadn't been criminally negligent in maintaining its equipment, this never would have happened.

Lead shot and bullets (especially copper-jacketed bullets) aren't terribly dangerous as far as lead exposure goes, since the elemental lead used in projectile construction isn't as bio-available as its derivative organic compounds (like, say, lead acetate or tetra-ethyl lead).
