(In a previous column, I commented on a landmark medical study tracking cognitive impairment -- this means impaired judgment, something which plagues many midnight-oil-burning white-collar workers. Sleep deprivation can have significant adverse effects on performance...in all sorts of contexts...and can be a leading cause of some legendary misstatements and other failures to communicate.)
In the meantime, consider the growing trend to criminalize all sorts of actions. An accident, including a potentially tragic automobile accident, can yield criminal liability as state legislators seek new ways to grab headlines and exploit popular outrage (of the moment) by thinking of new things that can be called "crimes" -- and which justify in the legislators' eyes punishment up to and including incarceration.
The lesson: Use the proper due care. But even if you do, an unfortunate accident can put you and your freedom at the mercy -- and subject to the malice -- of others.
