You are correct sir. This is also not the first "event" that did not align with the official narrative. To be frank I don't recall a recent mass shooting(or even Bombing) that I believe went down the way that it was reported to have. Far to many fall on days/weeks that training scenarios were publicly announced then recanted. (Even during nine11 there was a massive war game scenarios where terrorist were hijacking planes to ram into building. This caused all the active duty military at the time to assume that the distress calls were part of the "war game." I let people come to their own conclusions, it just helps when we know the actual facts. Not just what the propaganda machine puts out.)
As concerning a ban on "assault rifles," this ban would be one on the "look" of a weapon and not the functionality of it. In relation to "tighter regulations on being allowed to own a firearm," at least in the US, the opposite seems to be more effective. Look at D.C. after banning all handguns from law abiding citizens, the violent crime and murder rate exponentially rose. On the contrary the state with the most lack gun laws Alaska has had no mass shootings, the few gun fatalities in that state are usually resulting from excessive alcohol consumption and not premeditation.
These mass shootings, if they are in fact happening as they say are always in "gun free zones." I don't recall any events occurring in open/concealed carry areas. It's always in places that guns are prohibited. If we truly wanted to be effective in gun control it's simple. A trained and armed populace, will prevent these events in the future, also violent crime would drop to near zero. But that is just my opinion based on logic, historically events, and human nature.
The truth is many people are afraid of firearms, because they know nothing about them. I would recommend everyone when presented with the opportunity, to experience firing one. They are merely a tool, albeit a very effective and deadly tool. They can kill and they can stop killers, it's all in the hands of the user. I'm just very uncomfortable with the "state" being the only one who is authorized to use them. It was an effective means in to prevent opposition in pre-WWII Germany. I'd rather not see that happen again.
