Really cj?
Your logic is what? Other than complete BS not backed up by any facts.
Here is all the information broken out in easy to read form.
http://www.fbi.gov/ucr/05cius/offenses/expanded_information/murder_homicide.html
68% of all murders in 2005 were committed with a gun.
In table 9 you will find....
Only 754 of total murders were juvenile gang violence.
From table 8
There were 3,605 murders of those under 22.
68% of those under 22 were killed with a gun. But that includes infants and children not teens.
table 8
In the ages from 13-19 82% of those killed were killed with a gun. (It seems Blacksmith was off on his stat. He was too low when he said 80%)
So, even if we assume that every juvenile gang killing was someone in their teens, (Something we know is not true. I can find multiple stories of children younger being killed in the crossfire.) that still only accounts for 41% of the murders of teens.
