I agree with all that. Maybe the word isn't "blame," then. Surely there must be some code, perhaps moral or ethical, but ideally more rigorously enforcible, which ought to prevent the development of intentionally deceiving tools. Sure you could say this about all software, but that which can cause actual physical harm ought to be held to a higher standard.
Yes, unfortunately technology is advancing faster than the average human brain evolves more neurons, so it will only become less comprehensible to the average person.
That's setting aside the tendency for police to hire from the left side of the bell curve to avoid independent thinkers that might question authority, refuse to do bad shit, etc.
