Oh, for sure. Just look at the problems with mass stabbings in Asian countries:

The problem in America is two-fold:
1. People go crazy & kill people (which happens everywhere around the world)
2. Semi-automatic weapons are often used & make it easier to kill more people faster. Case in point, the shooter in Florida used a semi-automatic AR-15 to kill 17 people in 3 minutes:

Which, of course, can be argued either way:

What it boils down to is that it's not so much a matter of getting rid of shootings 100% (because that's impossible), as much as it is attempting to reduce the issue, because:
1. We need to take action to solve our problem of mass school shootings
2. We can't stop people from making bad decisions
3. We
can reduce how often it happens & also reduce the number of people who get shot when it does happen, which is far better than doing nothing
I bring up this example all the time, but in high school, I did my senior thesis on car safety. I was shocked to learn that we kill over 30,000 people a year EVERY YEAR in America in car accidents. That's INSANE! That's more than recent wars! While we can't solve that particular problem 100% (yet), we
can introduce preventative measures over time, such as seatbelts, airbags, ABS, automatic emergency braking, OnStar help systems, etc., to manage that number. So it's more of an issue of managing it as best we can vs. completely eliminating it, due to realistic circumstances.
For historical reference, Australia not only banned the bulk of semi-automatic guns, but also did a mandatory buy-back, and they have not had a mass shooting using those types of weapons in over 20 years. The worst one I've seen in that country, according to Wikipedia, was where a guy with a shotgun killed 5 people. So again, looking at it from a realistic perspective: people are going to do bad things, and we cannot stop 100% of those things, but we
can take action to reduce how bad things are when they
do happen, because they will continue to happen, and we are pretty stupid if we take no action to work on resolving our problems.
