Re: Fix the problem - safely - then worry about legal / senior management
I managed my teams like that which worked well until the Council IT top tier management team changed.
Obvious failures by my team members were resolved and owned, as one does.
The new "managers" were not up to their roles as we accidentally exposed time after time, so they used any failures as an excuse to shuffle me out (downgrading, dead end career progression, reorganisation etc).
They then promoted the worst members of my team into the team leading roles.
Karma being what it is, the management team all went on to enjoy massive salaries and pension benefits whilst the service and standards provided by the Council declined from the best value in England ( or thereabouts when I left) to the lowest levels possible.
It was always someone else's fault and they were such good managers they had managed to recover from some of the issues etc.
I can quite easily understand them taking hours to figure out how not to accept any liability at their level and getting that aspect sorted first before actually looking at the problem and ways to resolve it.
