1984 did not spring up over night. Every step Orwell's world took to Big Brother was one on the oard of good intentions. It was not until the populace had lost all that they asked "how could this be".
So it is with EDRs and such. Good intentions and see? They helped in this case. Today
Tomorrow? Some politician is going to pass a law that says "hey! The data is there, lets just read it to see who is speeding - speeding costs lives too!". And so it starts. (Actually it started a long time ago, but you do not see the incremental creep of the tide until your standing in the water.)
On that we will never agree. Just look at Social Security. And what it does now, and what the law was written to require of that number. I dont think we may be going on a slippery slope. I maintain we are already sliding on it.
