No, no, no. Check your statistics!
Lightning kills ~20 people per year in the whole U.S.: https://www.statista.com/statistics/203715/injuries-and-fatalities-caused-by-lightning-in-the-us/
That's comparable to the number of unarmed black people killed by police (source: the article you linked to!).
The total number of blacks killed by police is closer to 200 (https://en.wikipedia.org/wiki/Police_use_of_deadly_force_in_the_United_States, for instance, noting that the table is under-reported and correcting for the total estimated by the Washington Post).
The expected number of black people killed by lightning, assuming that lighting is race-blind, is 3.
So blacks are roughly 100x more likely to be killed by police than by lightning.
