Try weights and volumes:
1 gallon = 4 quarts = 8 pints = 16 cups = 128 ounces = 256 tablespoons
1 pound = 16 ounces = 256 drams

The core is there, we just need to rationalize it further.

A yard isn't that far from 2^5 inches.
A mile is already pretty darned close to 2^16 inches.

And, surely you're familiar with the rounding errors involved in trying to represent base 10 decimals in binary? That is, no finite representation of 1 cm in meters? 1 1 cm = 0.0000001010001110101... m

Face it, base 2 measures are superior for our computerized society. I'f we're going to switch measures in the US, let's go with a system which recognizes the problems of base 10.

And, using the base 2 advantage, it'd just be shifts for a computer.
2' 8-3/8": 100000.011 inches (binary)
mid-point: 10000.0011 inches
4' 7-3/16": 110111.0011 inches
mid-point: 11011.10011 inches

It's 11011.10011 - 10000.0011 inches from the wall or 1011.01101 inches or (in decimal) 11-13/32". No floating point rounding errors.

After all, Imperial (in the US flavor) is better for computing than metric since it's at least partially base 2.

We know exactly where they all are, including the one Iran just captured.

I'll always shop locally for books. There online experience doesn't compare to browsing a bookstore.

I'll also particularly support my current local bookstore for their excellent program of sci-fi/fantasy book signings with such authors as Jim Butcher, Patrick Rothfuss, and Brandon Sanderson as regular visitors. In the past year they've also had George R. R. Martin, Cory Doctorow, Kevin Hearne, John Scalzi, Terry Brooks and Orson Scott Card.

They're also pretty popular for signings in other genres. Not bad for a local (well, now regional chain but started here) in a smallish mid-Western/Southern city: Joseph-Beth Booksellers in Lexington, Kentucky.

Amazon can't do that.

Not that simple. There's 100+ different sales tax districts in the state of California alone which would need to be looked up by street address (or at least 5+4 zip, but I'm not sure that's a safe assumption) not by state or even county. Add to that an address in California can be within multiple sales tax jurisdictions with portions of the total sales tax getting sent different places. Amazon might need to collect 7.25% for people on one side of a street but 8% for people on the other and the next block down 8.5%.

This pretty much covers it. You might be able to get away with a solar powered airship, but nothing like the current speed of air travel.

Possibly.

The legal standard in most states for the use of deadly force is belief of imminent severe bodily injury or death. Essentially, would a reasonable person believe they might die or be severely injured and that use of deadly force would prevent it? States differ on what other avenues must be attempted prior to the use of deadly force, such as trying to run away, etc.

You can die in a fist fight. You can certainly sustain severe bodily injury.

There's another issue here. In most states, the initiator of the use or threat of force can't claim self defense. So if I punch you and we start fighting, you could then claim self defense if you shot me, but I couldn't if I shot you. The same if I pulled a knife and threatened to stab you.

And thirdly, there's the difference between what's moral and legal. There are probably situations where I'd think the person's choice to shoot was morally despicable but should be legal under the general principles of self defense.

Which is immaterial to whether the defense should be able to look at it for potential use. You're talking about prior restraint because they might use it in a particular way even though there are legitimate reasons to investigate it for use.

But generally not on self-incrimination grounds, which is the protection the Miranda warning about "anything you say" is about.

Why should they need to have prior knowledge?

In an fairly extreme example: if I post on FB about my martial arts hobby that I'm going to go out and beat some random guy on the street up. Then I'm shot dead out on the street. Then the shooter is prosecuted for shooting innocent me with wide reporting of how innocuous I was. Then it's certainly reasonable to use my prior statements displaying bad intent to call that description of me into question and of my martial arts training to suggest capabilities beyond what might normally be expected of someone my age and appearance.

I don't know all the details of this case and almost certainly neither do you. But it's ludicrous to suggest prior statements are only relevant if the defendant knew about them beforehand or can't be used in this situation under some misunderstanding of the constitutional protections of free speech.

Tweeting and posting Facebook are protected free speech in the US. They are also generally public speech and can certainly be used against you as a defendant in criminal court if the content suggests illegal activity. The First Amendment protection is only against being prosecuted for the speech itself. The Fifth Amendment protection against self incrimination doesn't apply to such public, voluntary statements.

But, ultimately that doesn't apply here since Trayvon isn't the defendant. This is about the use of public statements by the other parties by the criminal defendant. Miranda warnings don't apply here. They apply when the police arrest you and presumably charge you for a crime. When did they arrest or charge Trayvon?

Smarties!

Actually, most newer subs from any country don't have aft tubes, not just the USN.
