Don't poke the bear.

Or an asshole neighbor.

.... they got what they deserved, but I believe they did get what they were asking for.

The Goys were looking for trouble.
When asked to stop, the Goys escalated.
When the shooter (illegally) threatened lethal force, the Goys called his bluff and lost.
While their deaths were not legally justified, had the Goys been good humans they would still be alive.

They all foolishly ignored USMC Rule for Gun Fighting #26:
"Your number one Option for Personal Security is a lifelong commitment to avoidance, deterrence, and de-escalation."
https://www.snipercountry.com/gunfight-rules/

PA's stance on fighting words is that they constitute assault but in no way justify a violent counter-assault.

The Goys were clearly playing with fire and started the altercation. They are however, IMO, 100% blameless in the shooting response they instigated. There are few cases where breaking the law (the Goys did break the law) could justify a violent response but this is not one.

Apparently these parties were engaged in a long running feud and this fight brought things to the boiling point.
I would also highlight that any prior events (possibly showing Spaide or the Goys) are not included in the article. The fact that the feud was known to neighbors also demonstrates that rule #22 ( "Decide to be aggressive ENOUGH, quickly ENOUGH." ) was ignored by both parties. Obviously they had mutual grievances which would have better off being mediated.

Reasoning:

1.) Goys cross the street to throw snow onto Spaide's property, not an accidental act at all.
2.) When asked to stop (Within the purview of Spaide's rights re. his property) "The Goys yelled at [him]" rather than just not going out of their way to throw snow on Spaide's lawn
3.) Mr. Goy throws "A tool" at Spaide; Could be a snowbrush or a shovel or some combination thereof. Possibly something dangerous but realistically probably not.
4.) Mr. Goy then threatens Spaide and advances towards him with a raised fist, a pretty obvious indicator of impending violence.
5.) After Spaide retrieves a firearm, the Goys do not back down and continue to escalate the altercation (from the middle of the street, for whatever that's worth.)
6.) Finally, after all this, Spaide takes an aggressive action and opens fire.

If we're to believe witnesses and apparently the security footage, at no point prior to the shooting is Spaide an aggressor, only exercising his rights to ask these people not to shovel snow into his lawn. Yes, it devolved into a mutual screaming match, but this all could have been utterly avoided had the Goys not proven to be insufferable and petty children time and time again; Namecalling, screaming, throwing shit, threatening violence. I mean, I could be off the mark, but I'd rather not look up the video footage myself; I've been to the dark parts of the internet too many times and I'd rather be a bit uninformed than go seeking a low-quality snuff film.

It takes a special kind of stupid to think that these people were "Blameless". Did they deserve to get shot? Fuck no, but if Spaide didn't do it, there's no doubt in my mind someone else would. Shame about the Goys' kid... Gonna be messed up for a while. I hope he gets the help he'll invariably need.
