Guns have to be just in the hands of mentally stable people, everyone mentaly stable must have the right to have a gun, that means that we need replace the guns paper permit to a psychiatric exam to evaluate the future gun owner, with this solution we wont be a dystopian society!
I have noticed that gun crime have increased in the United States and it was due to the liberty for common citizens to have their own guns. The government have to tackle ways on limited the right to the use of guns and ammunitions by citizens.
Crime would always increase with time when it seems like everybody is holding a gun which could be a sense of self defense but that might be more than that. Some still use it for atrocities and cause conflicts to others.
