You know, I wasn't going to respond to this, but what the heck:

July, 1930 - Anytown USA

"Criminals Use Electronics to Foil Police"

The increasing use of electronic communications by police and other law 
enforcement bodies has lead criminals to engage in methods to
  interrupt and eavesdrop (listen to) those communications using 
off-the-shelf or home-built devices.

Emerging retail outlets such as "Radio Shack" (Boston, Ma) and "Allied 
Radio" (Chicago, Il) have facilitated such criminal activity by
  providing not only complete radio receiver sets, but components such 
as vacuum tubes, condensers, resistors, and such that dedicated
  criminals can use to build their own specialized devices.

Even a simple "crystal set" can be modified by interested criminals to 
listen to police-radio frequencies.

This is a worrying trend, and regulators are busy considering ways to 
put a stop to it.
