Input: There are just two plausible targets for a lawsuit  legal experts say:  Kelley âs estate and the Air Force. Suing for  Kelley âs assets would be an easy legal win. But it is likely to result in payments of no more than a few hundred dollars to each of the families whose loved ones were killed or wounded.
At issue would be Devin Patrick Kellyâs purchase of the Ruger AR-15 used in the attack. The Air Force did not report his 2012 court-martial for abusing his wife and her child to a federal database used for background checks on gun purchasers. Had that conviction been entered into the database  as required by Pentagon rules  Kelleyâs legal purchase of any gun would have been denied.
 Kelley   who worked in logistics at the Holloman Air Force Base in New Mexico starting in 2010  was given 12 months of confinement followed by a bad-conduct discharge in 2014.
Government attorneys would have to concede the Air Force error made it easier for  Kelley  to buy guns. But  they  would almost certainly argue in court that  by any meaningful definition of cause and effect   Kelley  caused the deaths and bears sole responsibility for the killings.
