Consider this man-made episode as a calibration of the "small impactor" end-member for NEO impact. A whole heap of stuff fell out of the sky and made a good try for some population centres.

Nobody got touched.

it wasn't a random fall - it was aimed!

Here is the nub of EP's wailing about the sky falling.... Most of the time, nobody gets hit, and nothing happens.

But every 1, or 10, or 100 Ma, shit happens, in a big way.

How do we calculate statistics in this case? The average damage is less than road traffic, or hand guns, or diving into shallow water while drunk.

But it just "might" replace mammals by cockroaches.

No easy answers, but EP, shrieking that "the sky is falling" is not a probable scenario towards effective resolution of the problem...
