Quite right.
However, the flt crew are only one layer of inspection. The engineer who opened it is responsible for ensuring it is closed again, either by them selves or make a tech log entry for another engineer to close it. It is also normal for the pushback crew to c/o a panel insp and confirm to the flt crew that all are closed and latched. The whole idea of this is to try and stop the old Swiss cheese problem.
I know the V2500 cowl and latches are an inferior design compared to the CFM cowling, but every one knows it is, so should take extra care when checking them.
At the end of the day all things taken into account it comes down to self preservation, it saves an awfull lot of paperwork and greif.
