Given that most mass-murders within the past few years, including the Sandy-Hook Connecticut school tragedy, were conducted by young adults with an age of 24 years and younger, we hereby petition that the government would increase the age limit to buy a gun to twenty-five years.
Here is a list of recent school shootings. Most shooters were under 25 at the time of their crimes.
