New York cops are very specific in terms of the way they talk and the way they handle themselves. All these cliches that, as an Englishman, I thought were from a bygone era or were a bit of poetic license with cop shows - the more you hang out with them, the more you realize how real that jargon is.
I say it is indispensable to look ahead of and behind oneself in the present. If there is such a thing as tradition, and I believe there is, it can only exist in the sense of the most profound movements of culture.
