I find that all this call about Minister being responsible is not without merit, however the issue is "how" is the Minister going to be responsible, not only for the fact that Mas have escaped, but more importantly what's the follow up action(s) taken to correct the situation. (In this "correction", it also also implies re-capturing of Mas).
The first point of failure in Mas escape can be mitigated in such that the minister is not ommipresent. As such the COI have sufficiently answered it's shortfalls.
However, it leaves the second point much to be desired especially attention and focus was specially given after mobilising so much resources. I believe such level of mobilisation would only be approved at ministerial level.
