Oh Agreed. No question at all. Except some claim "The boosters crossed
within the fireball", "The Pad was not ready to support the launch",
"Uncommanded RCS firings during Launch", and lord knows what else.

According to the aforementioned "JTM", "NASA's fault-tree analysis
failed to consider that space shuttle Challenger's solid rocket boosters
could have crossed paths within the 51-L fireball. A crossing
necessarily negates the Rogers Commission's postulated "right-aft O-ring
burnthrough." (from http://www.mission51l.com)

Only if there was no configuration control in the build process. Possible but unlikely.

Components would have some ID to permit tracking through the (re)manufacturing process. This would permit NASA (or their subcontractors) to know which bit was in which booster. It is most unlikely, in fact all but impossible, to believe that NASA decided which booster failed by back tracking the flight path to the recovery point. So, a missed "cross over" wouldn't matter. JTM seems to have a superficial knowledge of quality controlled manufacturing processes.
