I did some research, and I stand corrected.
However, I would like to point out that the (US) courts have affirmed the right for companies to sue for accidental cross contamination, even if to date none have done so. So the point about legal exposure stands.
I still believe it’s a dick move to plant GMOs in a residential area. Disregarding your personal opinion, your right to plant them or even the science, how would people living inside the range of corn pollen (~1.5 miles) feel if you informed them their corn might be pollinated with yours? Do you feel comfortable telling your neighbours what you’re doing?
