Maybe its not that engineers have a terrorist mindset but that terrorists get engineering degrees so they can blow stuff up
but i doubt you will become a terroist just because you're smart and have an engineering degree. and then there's civil engineers and people like them. i doubt that they would know how to make a bomb so its doubtful they are terrorists, very good ones at least. plus lots of terrorists are just random people from all parts of life that just have some beef with government or something.
