Random thoughts just popped in my head and I just remembered that all the water in a given city is all centralized. Just add poison and boom, eradicated an entire city who are full of dissidents/opposition as punishment for voting the “wrong” way, or for a protest, or if the population is filled with “filthy undesirable [Insert Racial Group Here]”, or something like that.
Kinda unsettling to see that we are all just attached to “the grid” 😖
Just worth pointing out, changing water source in Flint Michigan and not adding corrosion inhibitors seemed to do an excellent job for a short period.
Oh yeah, that is the other way of poisoning a water supply, sabotage it so that it keeps poisoning itself
