Plausible, but you are correct - the real answer is far more bizarre!Is it possible that Smith noticed his wallet was missing, and punched Smith after assuming he was the pickpocket?
That's probably not bizarre enough.
Tis true. Although not critical to the answer, both Mr Smith and Mr Jones are liberalsMr Smith is obviously a right-wing nutbag and Mr Jones a left-wing fruitcake. Mr Smith therefore blames Mr Jones for inducing angina, and makes vigilante response.
Political extremism is always bizarre!
