I simply can't believe that there were as many sick and twisted individuals in the world 50 years ago, as there are today. To be sure, there WERE sick people out there....but I really think that society, and what we deem as normal and harmless today, is encouraging this darker side in people. Take TV, for instance. What was on TV in the 50's and 60's? Look at TV commercials. Look at the types of shows that are on today ("Dating Naked", for instance). Look at children's clothes. I refuse to buy my girls shorts with words written across the butts. Why? Because it encourages people to be looking at their butts, for one thing, and secondly, it encourages the wearers to say, "hey, look at my butt, read what's there, it's ok....."
Look at old game shows, or variety shows. What people laughed about then wouldn't even get a giggle today. Today, it has to be lewd or at the expense of someone else to be funny.
You may think, "But I can think for myself! I'm not going to let myself be influenced by TV". It's a slippery slope. It's kind of like the frog in the pot of boiling water. It's possible to become desensitized to things before you even realize it is happening to you.
I remember seeing footage of the Hindenburg disaster. Listen to this newscaster:

He was in tears, it moved him so.
Compare that to how our news is delivered today. The most heinous acts occur, and our newscasters barely bat an eyelash, much less show emotion. Why? They've become desensitized.
When you say the statistics are the same, what statistics are you talking about? Abductions? Murder? Rape? Do you have a link to those?
ETA: I've seen the numerous stories that say we are just as safe now, as we were in 1968, that crime is no more or less.
I don't know...maybe everyone was just ignorant back them ("as in, ignorance is bliss", not meant as an insult).
