Here's a more to-the-point article (Warning: comment section gave me rabies)
Glad this guy was caught and glad you're alright Cousin Earl. Wonder what his motive was, though - he must have been one pissed-off bacon to target cops. It'd be kinda hard to pull this off without premeditation too so I wonder who knew this was going to happen in advance - if anyone - and why they didn't communicate it to the police.
That said, I wish the media didn't publicize mass murderers so much. It encourages copycat incidents and doesn't do much more than fearmonger and encourage legislation which takes everyone's rights away while the criminals don't give a damn and still find ways to arm themselves, because what criminal reads the law to make sure what he's doing is legal, right? Murder's been illegal since early civilization and it still happens regularly.
If he's ex-military, I heard service dogs are great for people with PTSD. Too late for that, though - he made his bed and now he can rot in it.
Oh, and @Cousin Earl, better safe than sorry on my part to bring this up: in the off-chance you find a gun on your property left over from this guy, or if your friends find one on theirs, or if you see one anywhere in the area: do not touch, and look for an adult immediately. Always assume there's a round in the chamber and exercise common sense with it. If they don't know how to make a gun clear without discharging it, tell them:
1. Never point it in an unsafe direction
for any reason - I don't care what your excuse is. Seems like a common sense thing but someone muzzle swept me with a shotgun Sunday because they were irresponsible, so... yeah. I can't stress the importance of high attentiveness when handling firearms. They aren't toys.
2. Eject the magazine FIRST (if there is one)
3. THEN open the action (e.g. for bolts, just pull the bolt handle up and back) to eject a cartridge that could be in it, and then notify the police.
If the magazine isn't taken out before opening the action, it will keep feeding rounds into the chamber. If you can't find an adult and you don't feel comfortable making it safe/don't understand which parts do what, then just don't touch it, period. Call the cops immediately and try to make sure nobody gets their hands on the gun while they're on the way.
Just look above you...
If it's something that can be stopped, then just try to stop it!
