The only part I kept hearing in reports was that advertising aimed at kids was a big factor but no specifics. How bad was this advertising that it could be implicated as causing or encouraging that kid to go kill a bunch of innocent people?
After a one-year investigation and producing a report on the massacre, the police never found evidence that provided a solid motive for the shooter's decision to go to Sandy Hook Elementary School that day.
In the meantime, the speculation and blame-games have never stopped. In 2012, several firearm manufacturers agreed to pull a variety of firearm ads from all sorts of media forms at the request of the state and federal government. This may have been construed by the plaintiffs as an admission that the ads factored into the massacre somehow.
Some of the pulled ads showed a woman in a bikini running from zombies who had just broken through her poolside fence.
Another had you take an online questionnaire, and if all your answers didn't focus on firearms being a positive force in your life, then you'd have your "man card revoked."
Many showed firearms as just something fun to own and use, as well as something the whole family could own and enjoy -- including the kids.
This link shows quite a few ads over the many years, and some of the more recent ones that were removed in 2012.

There was no actual evidence the ads in any way influenced Lanza, and at the same time, the manufacturers could agree some of the ads were unrelated to actual, legitimate reasons why someone would want a firearm. I think they are unrelated to the shooting, but appearances are everything when it comes to juries and stockholders.
Plus, Obama made the gun makers super wealthy right after the Sandy Hook shooting by vowing to ban "Assault Weapons." It was almost impossible to find any ARs, AKs or other "military style" semi-auto rifles in stock after that first week unless they were priced at 2-6 times the MSRP. I think the amount the manufacturers settled for was a drop in the bucket compared to the revenue the "Obama Gun Sales" years made for them.
