That's like saying "it's not about guns but killing by guns".

If we could only identify those pesky people that will kill with their guns before they do it, we could solve our problem! Just as if we could separate out only the drivers that will crash before they actually do it.

Alas, while you can probably speed many times without serious consequences, shooting someone without serious consequences is far rarer! This means we at least have a chance to catch the repeated speeders before they do irreparable harm, but we rarely have the same luxury with shooters.
