I listen to Radio Classics on XM, the radio programs from the 1930's until the early 1960's, before people watched TV all the time. On most of the "Cops and Robber" and "PI" shows, a common theme was "Shoot first, ask questions later". I don't know if this was just theater, or if it was taken from real life situations, I tend to believe it was the latter. I do know things have changed over the years, Miranda rights, shooting policies, etc. These changes probably came from instances like this when innocent people lost their lives due to Police over reaction. So maybe the "Good old days" weren't so good if the Cops could kill you just for running from them.... Selective memory always selects the good times, not so much the bad. I don't know what caused these lines through everything?
