TLDR Godwin's Law except every action becomes the act of murder.

Do I really need to say that ecological impacts and murder are very different things?

The funny part is your "murderer in the next town over" example is almost exactly how cap-and-trade works (plus a price mechanism), which is the most effective system yet devised to reduce smog from power plants. So in this area of public policy we already let off the "murderer" (eyeroll) with that excuse, and rightfully so...
