What's the Definition of a Nanosecond?

It's the time it takes for a liberal to go from 'good intentions' and "what could possibly go wrong", to "how could we have possibly have known".

Example here-George Jonas on the late Alan Borovy Z"L. 

"It always puzzled me why Alan, a civil libertarian by vocation as well as avocation, would burn the midnight oil to set up laws and institutions designed to reduce the very liberties he was safeguarding and promoting by day. The answer, it seemed, was that he never imagined human rights commissions, a progeny of the progressive left, could be a threat to free expression. In my column a few days ago I wrote: “It never occurred to [Alan] that civil liberties can be threatened from the left.”

"Initially, Alan, like many left-liberal social activists, believed he and his comrades could regulate conduct without affecting expression or conscience. After all, how could prohibiting discrimination in employment and housing turn into censorship in the media?"

"Unfettered by the illusions of the left, conservative civil libertarians could see it easily. Deny liberty to conduct; it’ll soon be denied to speech, or vice versa. Freedom is indivisible. Cutting it in half means killing it. King Solomon understood this in relation to babies; civil libertarians like Alan didn’t think it applied to civil liberties."
