> While I certainly blame the attacker for the actions they took, my root cause analysis places the blame squarely upon law enforcement for creating an exploitable vulnerability. The militarization of police combined with nonexistent authentication creates a great environment for SWATting.

People (like Lopp, according to his own tweet embedded in the article) own guns in the US and this is legal. Occasionally guns get used in some kind of hostage taking, robbery, murder, etc. I really don't think the blame lies with the police because they have to be equipped to handle those types of situations and that they (quite rightly) should assume every incident is real until proven otherwise.
