What conventional terrorism technique have I used? Here's an analogue of what happened. Bob says: yeah it's pretty easy to see that every even integer greater than 2 can be expressed as the sum of two primes.[1] I say: not so fast, you can't just claim things like that. I mean it might be intuitive or 'generally accepted' (and even stochastically probable!), but the truth-value of such a statement is difficult to prove. [1] Goldbach's conjecture.
