Really, this is news? I am far from the first to have already been pointing it out: when you give these madmen such staggering publicity, it gives other crazies the notion that killing a lot of people is a great way to get famous. Knock it off. Deny 'em names. Deny 'em fame.
Side note, the Norwegian killer was referred to by a newsie as "the worst mass killer of all time." Really? Stalin, Hitler, Mao, all the lesser murderers that ran their extermination systems, the human experimenters of Unit 731, they somehow don't count? Horror is, sadly, as quantifiable as any other human activity. And over and over again, the lesson is that you stop bad guys killing people by sending in armed good guys -- one at a time or whole armies at a time, it's what you do.

Speaking of which, there's dissention over the Californian ex-cop killer, who (probably) suicided while local police were in the process of burning down the cabin in which he had holed up. (Tear gas is flammable, how convenient). Plenty of folks think they should have set up a perimeter and outwaited him; after all, he was getting any resupply. Others are cheering on the burning, and deriding the first group as impractical fluffheads who care nothing for officer safety.
Couple of points--
First, policing is not really about officer safety; if the plan was to keep them safe, they'd armor up their cars and never get out. Cops, like it or not, are the pointy end of the spear. As a civil force -- not soldiers! -- they end up hanging on to the nasty end of that pointy stick; they don't operate in a war zone. Sometimes that means hanging back and waiting, when waiting will do no harm. (Look up the Indianapolis Baptist Temple situation for an armed standoff that just stood off until everyone was thoroughly sick of it and quit.)
Second, it is best if justice is done and seen to be done. The ex-cop in CA was pretty clearly deranged but burning him down leaves his claims standing unresolved. Getting him into court and either demolishing them as the fantasies of a diseased mind or uncovering a systematic pattern of racism in LAPD would still leave his crimes unjustified and he'd've been locked up for them essentially forever, even in CA,* but there'd be no question about the motivating circumstances and no halfwits standing up like he was some modern-day Spartacus.
Frikkin' work the system. You don't get shortcuts even if you've got a badge and a spiffing uniform. And you guys cheerin' 'em on, will you please take a step back and realize that while it's a good thing to stop a murderous madman, it's not an unalloyed good for the State to do so by means that are too easily construed as street justice without trial.
* While I would personally prefer "shot in the act by one of his intended victims" or a public hanging after a fair trial, you've got to take what you can get and locked away forever provides nearly the same societal benefit at relatively low cost.
