As a technically oriented and analytically minded person, I find myself making such determinations in a manner similar to the manner in which the late Supreme Court Justice Potter Stewart famously said he distinguishes between pornography and Constitutionally protected free speech: "I know it when I see it." Or in this case hear it. Although the results of such determinations tend to change every now and then.
