The challenge with all of this is that the ideas you proposed will have no effect on these situations whatsoever. Getting rid of these weapons will have no effect on these situations whatsoever because people will just get them elsewhere.
An example would be marijuana. For most of my life marijuana has been illegal. Yet almost everyone I knew in high school and in college that desired to smoke marijuana had a plentiful supply. But it was not permitted in the United States and through the just say no campaign and other criminal legislation it was vigorously enforced. It was also backed up by the culture and movies and TV shows as something that was really bad. Yet again as I said, marijuana was everywhere. Never was it hard to get.
I have no confidence that anyone would be able to stop the flow of weapons to the wrong people. Even with background checks and everything else that you mentioned. Even with waiting periods. People would just wait out that time and then execute their act of evil. What people seem to miss it seems like in my opinion is that the individuals involved are willing to die. The woman who committed this crime yesterday texted people she was about to die. This was what she wanted and if you're willing to give your life to do something horrible then it's very hard to prevent that.
That's why I always come back to our rotten culture is a huge part of the problem. And some of the statements made in this thread about there being war declared on the trans community and all that kind of idiocy only furthers the likelihood of future violence. It would be wonderful if people would learn to stop putting forward more desperation to situations. Isn't that what we're told on the other side? I'm so tired of the one-way street that we have with relation to these issues. Something is either right or it's wrong and it doesn't matter which party says it or which ideology it comes from. It's either right or it is wrong and it is that thing all the time.
Im not so sure ... where I agree that "Do something" isnt a plan, I do think some of the ideas presented in this thread (not necessarily mine) could at least mitigate some of the risk.
I have two ARs and I am quite proficient with both; so Im quite aware a 10 round magazine can be swapped quickly; however, in a situation where seconds matter ... a smaller magazine could mean the difference between life and death.
EDIT* and Im not so sure about your counter to extended wait times. Your counter is that of a rational person. These people are not rational ... we want to rationalize "Why did they do this?", but the only answer is because they are infected with evil. If a irrational/insane person has to wait longer, that is more opportunity for them to let the evil within them to be identified OR ... better yet for someone to reach out, show them that there are alternatives, and put them on a different path.
In this specific situation, we are now finding out that this person was under the care of a physician for mental issues. She was suicidal and her parents had encouraged her to get rid of her guns. She sold one and her parents thought that she had gotten rid of them all. She bought 7 firearms from 5 different stores all the while being under mental evaluation. Currently there is no "red flag" laws in TN that wouldve allowed law enforcement to seize her firearms, and I dont know if I would advocate for red flag laws, but I DO think it is worth the debate and discussion.
So the question remains, how did a individual who was suicidal and clearly mentally unstable legally purchase these firearms? I dont know man ... I just think its worth the debate. Unfortunately, neither side wants that debate, they dont want compromise, they dont want "solutions" ... they want the status-quo, because its great fodder for campaign finance.
One side says "Give me money and send me to Washington/State House and I will ban guns to protect our children"
The other side says "Give me money and send me to Washington/State House and I will protect your right to own firearms"
They know that both of these positions are non-starters.
They bicker at each other in the media, meanwhile the campaign dollars keep flowing in.
Youre right ... evil will always try to find a way, and for those that have turned their backs on God they are susceptible to this infection. Much to the chagrin of some, this is why prayer and openly sharing God's word and the love of Jesus Christ is so important. If it can reach one infected soul and bring them back from the precipice of despair, then that is a win. Its also important to not be enraged and to not "hate", because that is what this evil wants.
But, for something more tangible ... its worth the debate and ... we should demand that there is debate.
