I think it´s important to look at the data available to put things in perspective. Isolated cases and anecdote have limitations.
What is the magnitude of the problem? According to the Centers of Disease Control (CDC) "the
United States has the HIGHEST rates of childhood homicide, suicide, and firearm-related death among industrialized countries."
The evidence is consistent and overwhelming. Firearm death rates are the usual indicators used for comparison (Note: death rates are expressed per 100,000 children in each age group and for 1 year).
This CDC comparison (graph below) describes international trends:

The rate for firearm-related deaths among children in the United States (1.66) was
2.7-fold greater than that in the country with the next highest rate (Finland, 0.62).
Rates for
all types of firearm-related deaths are consistently higher in the United States compared to other countries.
• The
overall firearm-related death rate among U.S. children aged less than 15 years was nearly
12 times higher than among children in the other 25 countries
combined (1.66 compared with 0.14).
• The
firearm-related homicide rate in the United States was nearly
16 times higher than that in all of the other countries combined (0.94 compared with 0.06).
• The
firearm-related suicide rate was nearly
11 times higher (0.32 compared with 0.03).
• The
unintentional firearm-related death rate was
9 times higher (0.36 compared with 0.04).
Gun violence in the US has special characteristics. Unintentional shootings account for nearly
20% of all firearm-related fatalities among children ages 14 and under, compared with
3% for the entire U.S. population.
A recent Children’s Defense Fund report (2006) found 2,827 children and teens died as a result of gun violence in 2003 —
more than the number of American men and women killed in hostile action in Iraq from 2003 to April 2006.
• In 2003, 56 preschoolers were killed by firearms, compared to 52 law enforcement officers killed in the line of duty.
• More 10- to 19-year-olds die from gunshot wounds than from any other cause except motor vehicle accidents.
• Almost 90% of the children and teens killed by firearms in 2003 were boys.
• Boys ages 15 to 19 are nearly 9 times as likely as girls of the same age to be killed by a firearm.
• In 2003, there were more than 9 times as many suicides by guns among white children and teens as among black children and teens.
• The firearm death rate for black males ages 15 to 19 is more than 4 times that of white males the same age.
• There is inter-state variation. The seven states that recorded the most deaths among children and teens by firearms in 2003 were California, Texas, Illinois, New York, Pennsylvania, Florida and North Carolina. The state with the fewest child gun deaths was Hawaii with one.

Public health experts and officials agree with the diagnosis. The US has the worst indicators of gun violence among children and teenagers in the world. A different question is to try to explain the key determinants of gun violence in the US: Gun laws? Gun availability? Parents? Unsafe handling? etc. There seems to be some unique factors operating in the US. joeslifeyork has a good point in terms of the US overall rates of gun violence among children and adolescents.
