Calm down, surely the insurance policy will paid the damages. Or the Russian hadn´t a valid traffic license? Or the insurer is AIG?

[*ok...apologies for that. But it's apropo too, I think.... ;D]

Moreover, my own immediate reaction upon hearing about it was that there must be more to this story. I hold to the view that one or the other of the objects was "targeted," in fact, simply because space, even "near earth orbital space" is still a very, very sparsely populated region indeed.

I can understand this occuring due to human intervention. But it's very difficult to believe it occured due to random chance.

Ppl also win the Lottery, or get struck by lightning. No higher planning behind it, sometimes stuff just happens, no matter the chances.

Given the speeds the debries travels in orbit, sometimes even something small like a screw can cause major damage. There is an Annime called "Planets" toppling exactly that problem, telling the story of a space station in 2060 or something and a crew dedicated to cleaning up space debries for security sakes.

One of the Shuttles had one of its windscreens hit a few years back , NASA worked out that it had been hit by a flake of Paint! http://orbitaldebris.jsc.nasa.gov/ph.../sts7crack.jpg

Figure the odds on that one.There's a lot of crap up there and its suprising things like this don't happen more often.

There is quite a bit of stuff up there, but there is a way of knowing if a conjunction between 2 orbiting bodies will occur. Nominally, NORAD creates 2 line element data sets that commercial space users can use for this. I believe these sets are good for 7 days. Can't remember off the top. But this will allow you to reposition your asset days in advance if you detect a conjunction with something in your constellation.

And yes, Keplerian physics is driving this here.
