Earlier quoted context omitted.
Sure anyone could be hit by a car tomorrow. But why do we even bother to have education and laws? Why police officers and firefighters? Why EMT and doctors? Why don't we just let everyone die if there is nothing more that we could do? If there is only a 40% of a chance that a driver given a ticket will drive safer, then there is a 40% more likely for any individual to survive while crossing the street so we continue…
If we moved every man, woman, and child on Earth to the Moon, there's at least a 40% chance they would survive a catastrophic meteor strike to the Earth. That doesn't make it a good idea. There's always a cost and in this case (TSA or moving to the Moon) it's a ridiculously high one to pay for marginal protection against an unlikely event.
The conclusion that an attack is unlikely to happen is based on what? Can we do a fair experiment to show what would the probability be like if we never implemented this TSA inspection vs after implementing this TSA inspection?
Should we conduct such experiment and watch an alert (or wait until another plan gets hijacked)?
Okay. I need a new solution. What is the solution? I don't need a "we will die let's move on solution" because this is not a solution. If this is were a solution, we don't need law enforcement.
