The fact is that we could make this country safer by closing the borders, putting police on every street corner and creating a mandatory 6pm curfew for all citizens.
But I don't think I want to live in that country.
When I was a kid, our playground jungle gym was built on a bed of gravel. Falling off that thing meant getting cuts and scrapes that every kid got.
Now, jungle gyms are built over soft rubber pads or sand.
Now playgrounds are safer, but kids are pussies.
100% safety isn't necessarily a good thing. A few cuts and bruises can actually be beneficial in the long run.
Once again, look at WHY those things are in place. Liability. Fear of economic reprisal. We are our own terrorists. Lawyers and suing are far more terrifying to most than Abu Salami and his dagger of death.
