Gun violence has caused many problems in the past and is rising once again as a dilemma which has no easy answer to. Every shooting causes people to try and find the meaning and the murderer behind it. Gun violence has been dropping in the last 20 years. Before, it was higher than the average of 31,672 deaths every year. Today, there are only 86 deaths every day and no more. When schools waste their money on school security, nothing happens. Children are 100 times more likely to get killed out of school. Gun violence is also not because of mental illness. That means people choose to kill because they wish to. Mental illness also means people with delusions and/or hallucinations. Only a few had mental illness. Still, gun violence can be reduced even further by either the allowance of guns or the prohibition of guns. Scientific evidence has proved that gun violence goes down with safety rules on guns, but the debate goes on because of the Second Amendment and how some countries with guns have lower crime rates.
