I do think there are more then before

1st Population doubled and frankly % of good is down
2nd influence of Church Morals has declined greatly since WW2
3rd Lack of impulse control is viewed as an illness not evil
4th The law culture has tied the hands of the average Papa who in the passed probably could have shot and shoveled without anyone saying boo.
5th The lack or rigidity and TV/video on the kids probably makes it more likely they could be in an unsafe situation.
