"Just do something a large portion of the country would kill to stop from happening" isn't a good solution, but you know that. If reason was going to work, we would have used it decades ago.
Not much of a solution if you know it won't work. I'd still like to know what you propose someone with a crazy neighbor that wants them dead should do if defending oneself with a gun isn't acceptable.
We hear shitty "solutions" all the time, yours is nothing new. Most of this thread is just taking shots at us, knowing full well the solution isn't as simple as "just do what everyone else did" when other countries never had a gun problem like ours to begin with.
