"the feds will apply additional scrutiny to mergers and acquisitions"
With what manpower ? Will they be hiring additional agents to support the increased workload ?
I applaud the initiative, to be sure, but is sharing the data going to be enough to improve oversight ?
Because in the end, somebody is going to have to review that additional data, collate it and analyze it, and that for each agency involved.
Or there might be a joint task force for every case, to make the data sharing more productive.
In any case, it won't be simple, but it is a good idea.
