I read a story about someone showing flaws in a USA traffic light system and he was subsequently fined for "illegal engineering" which is the most idiotic thing ever.
Going on current USA progression it won't be long before you get 10 years behind bars for "illegal engineering" in some states.
Wasn't even that long ago. https://www.theregister.co.uk/2017/04/29/engineer_fined_for_...
