These things are acceptable – at minimum – to be used on human beings deemed to be enemies of the state according to John McCain, presumptive Republican Nominee to the Presidency of the United States (of America, I think). Threats to your family, if there is some reason to suspect you might be the enemy, are OK. Threats, presumably to kill your children, presumably to rape your wife, presumably to destroy all those things you’ve devoted your life to. These things are entirely appropriate, if you’ve been found by an arbitrary body to pose some hypothetical risk to the United States.
Waterboarding, on the other hand, is right out. That is, of course, if the Administration keeps its solemn and here-to-fore unsullied word that they won’t use it. If they don’t, thanks to his vote, there will be no legal protection for you under the law. Whoopsies.
