Everyone has lost focus on their objective. It's not what is common sense, it's not what should be done to stop these tragedies, It's not about mental health. No, what it's about, is closing the gun ownership loophole in the constitution.
Children being slaughtered by these savages makes me sick. In many cases this is facilitated by the access to unsecured firearms, other times it's weak a background check and / or no waiting period.
In Aviation, we look at an event and break it down to what lead up to the event. Often, if not always, if we interrupt the chain of events, just remove one link, the event is avoided, then we learn from that and move forward.
Trying to place myself in the position of a parent that lost their 8 year old to a school shooting (God I can't imagine) and thinking my child is gone forever because a child brought a firearm to school, in their backpack AGAIN, or a sick person, that everyone was aware, obtained a firearm from either securing it from a family member, stealing it from unsecured storage, purchasing it with out a decent background check, or having a friend that is aware of the persons mental condition and then providing a firearm to them, AGAIN. Makes me think , as a firearm owner, and a grandparent with 5 to 13 year old grand children in school, maybe it is time to not necessary have California style gun restrictions, but California style background checks and a reasonable waiting period.
That being said, it's not my desire here for forum members to think I must have been struck by lightening and went over to the other side, nothing could be further from the truth. Along with identifying the root cause that drives these savages to shoot up schools, we as firearm owners that don't want more restrictions placed upon ourselves, should demand of other firearm owners to do exactly what the title of this thread claims; common sense. Secure your firearms, train others, don't purchase or sell a firearm for someone that can't pass a background check.
Sorry guys, I am just sick of the shootings, and every time this happens it get's dumped right back in the gun owners lap.
