Like machine guns, they should be heavily regulated. It has been shown they can kill 50+ people very quickly. They are why we constantly have a new worst mass shooting.
Then according to your logic, all cars should be banned......the Vegas shooter, shooting into a crowd of over 22,000 people was only able to kill 58 people....a muslim terrorist in France, using a rental truck, was able to kill 86 people in 5 minutes of driving.....
Cars killed 38,000 people in 2017.
Guns killed 10,982 people.
Cars are far deadlier than guns, we need to ban them.
