Like I said, far less efficient and can only be used in very limited scenarios. Really only good for killing random people. If these school shooters had the desire and ability to take kids out with cars, why are they using guns?
Yes, it can only be used in limited scenarios.
No, it is not less efficient, only a few mass shootings are as large as the recent one, and the Nice attack, for instance, dwarfs that. As with mass shootings some result in only a few deaths, and some result in many.
And arson attacks, bomb attack etc., have also been quite deadly.
I think the bigger issue is that so many people have a desire to kill lots of people, whether they use guns or vehicles. They are still dead. We need to figure that part out.
I would propose in this case modifying Section 230 to require internet platforms to report known threats. His account was temp banned on a social network after threats of school shootings, threats of rape of particular people, etc. and he had a video on the platform of him holding two bloody dead cats in a clear plastic bag and laughing, saying he did this often.
That should be reported. And some of these interactions were a number of days before the incident.
They already still require platforms to deal with sexual exploitation of children content when it is known about.
