One of the comments in response to that article made a good point, and this perhaps is the nub of the issue, the situation in California (and increasingly the entire US) is not lawlessness. It's worse than lawlessness, it's unequal and selective application of law. The miscreants who have burgled Dr. Hanson's property are able to operate with virtual impunity. Even if caught they have the benefit of a sympathetic narrative in the judicial system, and given that the Black Robe Mafia has already ordered the state to set free 40,000 prisoners due to the horrors of overcrowding, the odds of actual prison time are nil. Now, contrast this with the Hammer of Thor that would be dropped on any decent citizen who defended his property and livelihood, particularly if the criminals were of a protected species.
The productive class no longer has any defender, and is furthermore actively prohibited from defending itself.
