In your world we have infinite numbers of agents, and infinte dollars, and federal investigators. In the real world, we don't, and when they are forced to investigate non-crimes it detracts resources from real threats. I'm sorry you believe the government can protect you, but they can't. An enemy within our borders who is determined to kill WILL be succesful, it is just a matter of time... there are infinitely many ways to kill, and our bureaucratic government is too inflexible to respond to this kind of threat. Resources spent on infiltrating existing networks and PROTECTING OUR BORDERS are much more effective than taking liberties and creating a police state. If that happens, they have won... If one wants to be very safe from terrorist attacks, live in any rural area, there is no benefit to an attack there.
I'd say they're pretty well ahead on that one already.
In your world
What do you know of my world? Nothing.
when they are forced to investigate non-crimes it detracts resources from real threats.
Do you know for a FACT this is nothing? No..and neither do I. But I would feel a lot better knowing for a FACT it is nothing.
One day people my become too complacent and when things go BOOM those same people will want to know why and why weren't we protected. Why did no one see or say anything. Just like those flight schools.
