That edit is an important caveat: the Starstreak is not a kinetic killer, but a kinetic penetrator. Half its weight is explosives, and after those detonate, the rest would turn into very small bits.
Of course an intact Starstreak submunition is very definitely something you that wouldn't want landing on your roof. But fragments from half a mile overhead? Not such a problem. Certainly not pleasant, and possibly a bit dangerous -- but probably no more than things that London drivers do hundreds of times every day already.[1]
