The times.
Airplanes were never before used to kill thousands of Americans. What changed? What did we do about it?
Fertilizer bombs were never before used to blow stuff up? What changed? What did we do about it?
CO2 didn't use to be a problem for earth, but it seems to be now. What changed? What should be done about it?
The reality is the world changes, people change, situations change, and we as a people have to be able to respond to the changes in ways that reduce the harm responsibly.
great analogy on airplanes - we hardened airport and airplane security , we didn't ban airplanes
we started tracking large buys of fertilizers and we placed guards at every federal building, we didn't ban fertilizer
You asked what changed, I said the times, and gave examples of other things that didn't used to be issues, but are now because times change.
We responded in ways that cut down on future incidents with bombs and hijacking. We're not responding to school shootings in any meaningful way because of the gun lobby. We're not responding to climate change because of the oil lobby.
Perhaps you think the solution is to make schools like a maximum security prison. That's an option. Another option is drastically reducing the availability of guns.
One of those solutions dramatically changes the way schools function and has really no benefit on other problems in society, (maximum security schools) while reducing the availability of guns would not only benefit school security, but would improve things across society.
Times change, new problems crop up, and we can:
1) respond in ways that make sense and help address the underlying issue
2) basically ignore the problem and continue to suffer the same or increased results in a hope that it just goes away
3) take some steps that seem to make us feel good that don't require sacrifice and don't actually do much good.
We're stuck going between 2 and 3, and the gun lobby effectively prevents us from going after #1.
