As said above, it's possible he was in fact ignored by The Racist Powers That Keep On Being. But given that it's the LAPD, I think it's more likely that they announced a reevaluation of the case in order to see if they could get him to come out. His manifesto is basically screaming that this keeps going until his NAME is cleared: if he feels it's happening -- or happens after the world's fastest not-review -- there's a tiny chance of surrender.I have seen some of his support comments. As typical for the Internet, a number come from trolls. I don't doubt he has fans, though. Plenty of anti-government types would love to kill themselves a few officers, and the fringe wouldn't have a problem with targeting families.
Whether he has supporters out there willing to hide him and go down with him -- longer odds. It takes very little courage to proclaim your hate in type and a lot more to use it as armor against SWAT bullets. Outside of scripts, he'd need a network already in place or the kind of luck you normally have to write.
Now, if he can get an untraceable login and start looking for his backers... that's when it gets scarier.
