Re: Laser

In principle, at least, laser works even better at night (less IR
background noise). Practical night use would come down to
the design of the aiming sight, which I had always assumed was
similar to a telescopic gun sight, and to interference from
automobile lights.  Regarding aim, it would seem quite easy to
place an illuminated cross hair between the head or tail lights
of a car as you squeeze the take-reading trigger. Unless car
tail lights generate more IR in a interfering band than solar
illumination plus IR re-radiation from the daytime landscape,
I don't understand why night time isn't the right time for
laser practice.

Nevertheless, like Steve, I too am hopeful that the natural human
tendancy to be lazy will limit the use of laser speed measurement.
In my experience, it's all most SP officers can do to leave the
radar switched on as they cruise. It's only when they're on
a planned speed busting operation or have had too much
coffee that they can muster the energy to push the instant-on
button.
