alt Hacker News- can you build bombs to blow up an apartment complex full of 1000s of people?
- can you poison the water supply of an apartment complex full of 1000s of people?
- can you drop a harmful substance using a $50 drone onto an open area where of 1000s of people have congregated?

This isn't a judgement on your general point, but I think bombs and bioweapons and etc are very bad examples for you here.
