True in a way :). As in "all of you are liars", when negated becames "not all of you are liars" - i.e. someone's asleep at the wheel today. It's a little tricky in the language, as the opposite of "all are" is not "all are not", but "not all are". The "all are not" is equivalent to "nobody is"... which is what you were already saying.

Let's take this from another angle. What makes a statement a statement? When does a sentence become a statement? IMO, it's when there's a claim in it, when it says "when... then IS true", or when it just says that something exists (ergo, IS). We can't havea sentence like "25 to life" taken as statements, because it doesn't claim anything. But if you toss in an existential verb (or whatever you may call it - my logic courses took place somewhere, but it (the place taken) stayed within the republic of another language, not English), you got yourself a statement, a claim. So while "25 to life" is not a statement, "the former government should get a life or at least 25 to life" is a statement - "should" is the verb, and negating that verb ("should not" - should be summarily, or productively, shot) gives you a negated (therefore logically opposite) claim.
