Why not both? Tackle guns with more control and better mental health care and education.

Disarming bad guys shouldn’t be the goal. Much like smoking in the UK. You wont stop all the older generationa from smoking but you can make it illegal for all the younger generations and over a longer peeiod of time theres no kne left that smokes.

If you tackle guns now and provide greater control over ownership whilst simultaneously educating younger people you will effectively prevent this sort of crim in the future.

At least thats my view.
