“But what do we DO about this!?!?”
Sometimes bad shit happens, and after the fact, there is little or nothing you can do about it, or should try to do about it. The obsessive, desperate need to “do SOMETHING!!”, as a result of some horrible event, is often just an emotional crutch–a way of trying to not feel powerless.
And a dead give-away that someone is in fear-reaction mode is if, while trying to “DO SOMETHING!!”, they don’t seem to care whether that “something” is rational, moral, or likely to even accomplish anything. When people have the attitude of, “We have to try SOMETHING!” as a result of desperation, anger, or sadness, that is their emotions talking, not their rational mind.
Every time something horrible happens, whether as a result of malice or bad luck, there will be a number of people clamoring for “government” to propose some new legislative solution. Rarely does it do any good, and often it makes things worse. But most people would rather “demand” some pointless measure, than face the fact that there is a lot about the world that is simply unpredictable and uncontrollable.
Prepare where you can, but don’t be surprised if the universe finds a way around all of your preparing and precautions, and bad crap happens anyway.
