The "</snark>" at the end of your post suggests to me that you think this is all some sort of joke.
Perhaps you'd find it just as funny if one of your loved ones, or their children was killed in such an incident. How much </snarking> would you be doing then..?
It's one of those terrible aspects of human nature that some people are completely un-bothered by dreadful matters...... all the time it's happening to other people.
I'm sure there are people in the world who you care about very much, and who care about you too, and as much as I would never wish ill on anybody much less to have them suffer something as dreadful as being caught up in such a mass shooting, such is the prevalence of these acts of insanity over there that the possibility of it happening to somebody you know sooner or later cannot be discounted.
Does the thought of that not fill you with dread..? I don't think I could comfortably live in such a society..... and I'm glad I don't.
It's not for me to tell Americans what to do or how to do it. All I can do is add my opinion on a public forum and hope that sooner or later there may be an outbreak of sanity.
And just to add one other thought..... what if a parent of one of the victims of such a shooting were ever to read you (or anybody else. I'm sure you and your opinion are not alone) making a mockery of their child's death. How do think they would feel...?
Have you no empathy..?
Would it be better to consider that as a complete solution?
Putting up signs and training our children how not to get shot?
That seems to be the thought of plenty of gun-nuts and politicians.
Hell - they even want to get rid of the signs and allow Carry Everywhere.
Turtle McConnell has refused to bring up a bill passed in the House (240-190 .. i.e. bi-partisan) in Feb increasing background checks.
... and I can't cry for everyone.
