Critical infrastructure was breached and the authorities' response was to go on a manhunt for people who were by that point obviously not a threat. All the resources that went into it had to be diverted away from other activities that might have had an actual positive impact on public safety.
If the authorities had simply launched an investigation into how the breach was made so that they could take steps to make our infrastructure more secure in the future, that would have been an appropriate and reasonable response. This wild flailing about, though -- all it does is demonstrate once again that the people in charge of our national security are incompetents who rely on security theater to maintain the illusion that they deserve to keep their jobs.
