@QasimRashid In countries where guns are hard to obtain, people make their own. Bombs are easy to make using ordinary household products. Same for poisons and poison gasses. Do we ban pantyhose because women get strangled with their own pantyhose? Do we ban cars because people drive them into crowds?
Address the issue - not the symptom. Shootings are symptom - not the issue. Address the reason WHY people are killing each other but of course it's the preferred tactic of spinless people to ban the tool and claim the problem is solved without having attempted to solve the problem.
