As expected, last week's "Sons of Anarchy" opener, with its disturbing school shooting, provoked widespread reaction -- some positive, some very negative. Series creator Kurt Sutter even got into it with the Parents Television Council, a watchdog group that called the episode "an outrage."

But on we go. As Sutter promised, the shooting continues to have an impact on the Season 6 storyline. In tonight's episode, "Six One Six," we learn that four are dead, including the shooter, an 11-year-old named Matthew.

Plus there's bad news for Jax and the guys: The gun used in the shooting was one of SAMCRO's -- a KG-9 that belonged to Nero's cousin, Arcadio, the boyfriend of Matthew's grieving mother.

Some viewers have criticized Sutter and his "SOA" collaborators of "glorifying" or "exploiting" the kind of murderous rampages that have occurred in our country all too often. Of course, they're doing nothing of the sort. That's a wildly simplistic take. If anything, "SOA" is leveling a vicious indictment against crappy parenting and, of course, SAMCRO itself.

Matthew's mother, it turns out, is a drug-user. The kid was obviously neglected and unsupervised. And surely, there was little, if any, attention being paid to mental health issues he may have had. (Just one look at his gruesome notebook doodles should have raised a red flag).

As for SAMCRO (and similar gun peddlers), there's clearly some disconnect between what they do for a living and the consequences that ensue. As Sutter told EW.com last week, they put the guns out on the street without really knowing whose hands they're going to wind up in and what violence they create. To me, that's a compelling -- and important -- story to tell.

Now back to that story: Jax is stunned by the news that a SAMCRO gun was used in the shooting. How can he not be? He's a parent. (Although, I would have preferred to see a little more soul-searching angst from the character). But he's also worried about protecting his own ass. He knows there will be major political fallout from the shooting, and sure enough, the episode introduces tough-talking District Attorney Tyne Patterson ("Shield" alum CCH Pounder), who is just looking for someone -- anyone -- to hang the crime on.

So Jax is desperate to keep Matthew's mother -- a "junkie rat" -- from blabbing to the Stockton cops. To do so, they abduct her from her home and take her to a cabin in the woods, where they hope to lay low for a while and convince her to keep mum.

But the plan unravels into chaos when she finds a rifle in a gun rack (Wouldn't the SAMCRO guys have cleared all that out?), blows some holes in the cabin and bolts out of the place with Arcadio. Just when it looks like they're about to get away in a pickup, Nero shoots his cousin in the head and Jax tackles the woman to the ground. Jax is ready to shoot her right then and there, but a mournful Nero pleads with him to spare her life. (Jimmy Smits does wonderful work in this sequence).

Jax relents for the moment, but there's no way he's going to allow this loose cannon to stick around. They tie her to a bed and, without Nero knowing, Jax sends in Juice to shoot her up with drugs. Then, in yet another harrowing "SOA" scene, Juice uses a pillow to smother the life out of the woman. Clearly the plan is to make it look like she died from an overdose.

In other plot developments:

-- It's no more guns for Jax. He wants to cut ties with the Irish, but it ain't going to be easy. He meets with the boss man Galen and offers a plan that would have the Irish Kings dealing with a San Bernardino biker crew. But Galen will have none of it. In fact the smiling thug in a suit sees a way to profit from the tragedy. He knows that, after every such shooting, many Americans rush to get their hands on the deadliest weapons. His cynical plan? Bring in even more KG9s and double the price. Sick bastard.

-- Tara's out of jail, at least for now. Her trial is six weeks away and things with Jax are, shall we say, awkward. He again promises that SAMCRO is going to go legit and he'll step away. Just not right now. Considering what happened with Opie, it wouldn't make sense to him. Tara's patience is wearing thin.

-- Clay tells Toric he's willing to rat on SAMCRO, but he wants to talk to Jax and Gemma first. When Gemma arrives for a jail visit, he tells her that "whatever goes down, none of it lands on you." And apparently, she still has feelings for the big lug.

-- The vengeful Toric begins to form an alliance with the DA that could prove beneficial for both of them, even if she openly expresses disdain for him. He'll go, unimpeded, after SAMCRO, and she'll get the public hanging she longs for.

-- Bobby continues to plan his new Nomad chapter, unaware of the crap storm his Charming comrades are about to face.
