As a time traveler, I've had the unique opportunity to be able to observe not only the happenings in this present day 21st century, but also to read up on past events — your "recent" history, dating back several decades or more. And the horrible truth is, people simply are not learning from past mistakes. The saying that "if you do not know your history, you are doomed to repeat it" is unfortunately coming true at an increasingly and frighteningly frequent rate. One shooting seems to beget another, and another, and another. And Congress is doing nothing to stop it!
I actually discovered another old example of what you call a "television" program from nearly 50 years ago which beautifully illustrates this shameful pattern. I invite you to click on the picture below to watch two famous storytellers of that period, Messrs. Rowan and Martin, as they bestow a special award upon Congress for its cowardice and inactivity.
Your humble servant,
