I agree with Curval, and my opinion is equally worthless. But I'm glad I went to school where and when I did. It was a much more civilised era, no violence, no guns.
The world HAS changed, and not all for the better. If the consensus in America is that schools would be safer if teachers were armed, then go for it. I personally have doubts, and as curval says, your liberal pinkos' mileage may vary. One thing I do know - it's a sad, sad situation when it comes to having to arm teachers.
As I look back over the years, I realise I had an excellent junior school education. Those were the days of being taught arithmetic, grammar, spelling tests, history... teachers did what they did best. They taught. I have an old school photo of the teachers at that school in the mid 1960s. I'll post it here.
One question: Can you imagine any of these ladies and gentlemen strapping on a snub nosed revolver to take class?
