As said before when you are lead to believe there is a threat lockdown, cancel flights and that buys you time to assess the threat and informs whether you can safely ease restrictions or strengthen them further.
If you learn an individual or individuals pose a potential lethal threat you put in containment that reduces the risk to others, formulate a plan and deal with it.
What you don’t do is let them wander about killing people for a few weeks while you sit around eating doughnuts thinking about what to do and then wonder where the hell to start your search for the bad guys.
