A major league outfielder (baseball) can determine where the ball is going to land without having to constantly adjust. He still has to visually track it to make fine adjustments since it is relatively small and very fast moving - just arriving at the spot wouldn't be enough to catch it. Visually tracking also allows correction for dynamic atmospheric conditions.

A basketball player is also able to predict with very close precision where his jump shot will land.

Per capita makes no sense either. By that logic, the US could be less of a poluter if we imported in millions of people from mexico and forced them to live off the land in areas without any electricity.

People from small european countries with homogeneus populations tend to rely on this "per-capita is all that matters" fallicy pretty heavily.

Many of those cannot be accounted for though.

Atmospheric conditions such as gusts of wind and air pressure are not exactly knowable at the moment the projectile will encounter them. Any solution would have to assume some level of uniformity.

The OP was referring to the altitude of the shell, not its range.

Law enforcement will convince the judge that having a plausible deniability volume is standard practice in the criminal world and the judge will hold you in contempt unless you unlock more than one volume.

Yeah, this isn't fair and you might not even have multiple volumes, but the justice system isn't fair. Judges get to do pretty much whatever they want when it comes to contempt.

You are only partly correct. A judge does have authority over you and he can lock you up for contempt for the rest of your life without a trial even if you are in the right.

The justice system will be aware of this feature and demand that you provide both passwords. If you don't, the judge can lock you up indefinitely for contempt until you comply.

One other statement that you can safely utter to the police without a lawyer is "am I free to go".

That may be, but it would it probably lead to less jail time than contempt of court.

States like Florida are able to collect enough sales tax from out-of-state tourists that they are able to avoid an income tax.

Sales tax is probably the most "fair" of all the various tax schemes as it is for the most part, an optional tax.
