Oh yeah and there is one more source that we are surrounded by all day every day. It is nearly impossible to escape. The 60Hz radiation from the power grid.
I'm sure everyone wants to forget the pain of the old days too. Installing trumpet stack on your Windows 3.1 box and then struggling for days trying to figure out what was going wrong. Oh and don't forget having to install the 32-bit extension on to old 16-bit Windows so that you could use NCSA Mosaic/Mozilla.
It would be like someone say I have a great idea for a computer. We shall name it UNIVAC...
The FTCA specifically allows claims based upon negligence to be brought against the Federal government. However, you are correct that this liability is limited by the exemption you have posted. I don't think that any reasonable person could suggest that if data were stored on a server at Google and distributed over an entire datacenter, that the entire datacenter could be seized. That exemption gives Federal employees the leeway to search a house they reasonably believe contains a fleeing suspect. It does not cover something like seizing all the cars on a block because one contained drugs. No reasonable person would suggest such a ludicrous argument in that case nor should anyone suggest that since these 100 or so servers are in close proximity in a data center they may all be seized.
