With all due respect Master Sergeant (and very much is due), the "22 A Day" is not what it appears to be. That number was derived from the VA's 2012 Suicide Data Report and it includes all suicides from ALL veterans of ALL eras of service.
For example: If someone served 4 years as a Coast Guard chef stateside during peacetime in their early twenties and then committed suicide in their late 60's it is counted as a "Veteran Suicide" even though the person's military service had relatively no impact on their choice to commit suicide. These events are the overwhelming bulk of the "22 A Day". The more accurate data that is relative to service-related suicide is <1 a day (still too many in my opinion).
Don't get me wrong, I am not trying to downplay the seriousness of Veteran Suicide, or suicide in general. For the last ten years and currently I have served as a family liaison and resource for several active duty commands and one of the areas we train in is suicide prevention/support.
But, the "22 A Day" phenomena being misused by the media and politicians will have more lasting negative effects on service members. If we promote the idea that military service=mental illness, depression, and suicide it makes it that much harder for service members to integrate into society as a whole.
