That's why Democracy is the worst form of government excluding the alternatives. But it would be nice to have a democratic government that is also capable of acting decisively. I don't have any ideas how you'd do that, but it doesn't seem wrong to express the desire.
Democracy being swift like autocracy is basically impossible. Any pretense of democratic government action needs the discussion to happen, which takes lots of time, and this makes the action not swift.
Instead, the way western governments seem to approach these crises is that lawful process is violated by the government more or less, tough dubious measures are introduced more or less in the interest of the country, then some people protest, maybe lawsuits get filed, then justice system gets bogged down for years, and in some cases we get rulings that government broke the law. This usually changes nothing.
