That's too funny....
Here are a few approx. figures to ponder from the US Census......
300,000,000 US Population
51,000,000 Hospitalized with a Major Mental/Physical Illness
14,000,000 Suffer from Schiztophrenia or Dimmensia at Home
80,000,000 Age 0-10 and 85+
2,000,000 Are in Jail
1,000,000 Are Blind
That leaves about 150,000,000 to 200,000,000 from the age of 11-84 whom are able to have a gun. So if 80,000,000 own a gun that's about 1 out of every 2 people that are age 11-84 and are physically capable of holding a gun, have one.
