People can buy weapons "off the shelf"

This topic is a hot potato, I think the Government of countries such as United States of America must have a better control on what type of person have access to buy a gun. People with mental disorders or illness should not be allowed to buy guns. The Government must make medical exams to people that are whilling to buy a gunfor being sure that they won't be a threat to the population.

I'm totally in favor on your opinion, it is important to control the traffic of guns, as all the genocides have comed a pain in the neck for countries as Unied states. The most important function of the government is protecting its people. That's why government must be more concerned of the problems that occur nowadays, for the easy way of purchasing arms.
