Well when industries don't self regulate governments step in.  This
industry is demonstratably incapble of regulating itself in this
area despite lots of evidence of the problems being caused for lots
of years.  This has been DOCUMENTED BEST CURRENT PRACTICE for 13.5
years.  Everybody else is having to deal the problems caused by
these bad actors.

Hell, I suspect you could send the directors to gaol or make them
pay a heavy fine today by properly examining the existing laws.  A new
law would just make the problem more explicit.
