4000 is only .0013% of the nations population...who cares. Everyone dies sometime...and, in the same time those 4000 died, hundreds of thousands of illegal aliens of the same age group flooded across the border....
I am not losing sleep over 4000 kids checking out...
I think the stats indicated that about 49 percent of 'youth' suicides were by firearms. That would cut your .0013 to about .0006.
It's my contention that gun control, even if the controls were only in force to keep the guns out of the hands of a kid who wants to shoot himself, would actually cause more deaths than it would save due to the inaccessability of the weapon when it is needed for its righteous purpose.
