“The real question to be asking is why now? Schools and guns were there in the 50s-60s-70s. What’s changed?”
That’s the $64,000 question! We used to have .22 rifles in our cars in the student parking lot in the 1950’s here in Northern California, no one was concerned, and no one got shot. Now, if the school finds a gun in your car, you are off to jail. Simpletons running the schools give you stupid answers, and they do so after listening to their “lawyers.”
“What’s changed?””
Overall, I’d say that, as a culture, we have increasingly ignored God and His ways. This has removed us from His protection and wisdom in a corresponding variety of ways.
