Soyuz TMA-12 faulty

Volynov on Soyuz 5 went so far as to stick his orbital log between his
spacesuit's inner lining and his body, so that it would have a chance of
surviving as he died during reentry.

And for that I salute him- that's Wally Schirra kind of thinking.

If that's the case, then the crew probably has at least a 10% chance of
being killed during reentry.

What's their % chance of being killed during a "normal" reentry?

52% of all statistics are made up.

The Soyuz 11 did a perfect reentry and landing, but unfortunatly all the
air had leaked out, so the crew was dead when it landed.
Then there was the one that rolled down the mountainside, and the other
one that descended into the lake.
Yet another Soyuz was supposed to have landed right next to a small
rural school.

Hand waving doesn't make for good statistics. Try again.

No one really knows just what abnormal events occurred on all of their
Soyuz missions, as they were mum about flight details during the Soviet era.
James Oberg took a stab at trying to get some quantifiable data in this

True, but it's very hard to point to a bunch of near misses and extrapolate
just how close the crews were to dying. That and these are the near misses
we know about. There may be serious problems with the system that simply
have not surfaced in the few flights that have been flown. And there may be
serious problems that have been presenting themselves, but no one has
recognized them as being serious.

The real problem with any safety assertion for Soyuz is caused by lack of
flight data. The flight rate of Soyuz is so low that it's extremely hard to
get a handle on just how safe, or dangerous, it really is.

Also, since it's expendable, it's per flight safety rate is far more
sensitive to production problems than a typical reusable aerospace vehicle.
The current problem with DM/SM separation appears to be just such a problem.
