Yes, I have. But as a point of note, it looks like they're just shoveling the snow across the whole street onto what appears to be an unplowed side walk. Sure, it's not their place, but this wasn't even remotely close to an appropriate answer.
Ahh yes, the proper response to "Go f*** yourself" is summary execution.
If you think this was by any means appropriate, you should probably relieve yourself of your guns before someone does it for you.
You're very conveniently ignoring the part of the story where he asked them nicely - and they told him to eff off - and this was all just a follow on chapter to what was apparently a long lasting pattern of shit between these people. I would also add - AGAIN - that what they were doing sure seemed to be ON PURPOSE, as in " where are we going to put this snow..... I don't know , how about on his property - just to piss him off"
Does all this add up to "deserve" to get shot? No - but it certainly adds up to a completely expected outcome.
