"Study reviews gun access, some owners’ rage" by Christopher Ingraham, Washington Post April 09, 2015
WASHINGTON — About 22 million Americans — 8.9 percent of the adult population — have impulsive anger issues and easy access to guns. Some 3.7 million of these angry gun owners routinely carry their guns in public. And very few of them are subject to current mental health-based gun ownership restrictions.
Those are the key findings of a new study by researchers from Harvard, Columbia, and Duke universities. ‘‘Anger,’’ in this study, does not simply mean garden-variety irritation. It means explosive, uncontrollable rage, as measured by responses to the National Comorbidity Survey Replication in the early 2000s. It is ‘‘impulsive, out of control, destructive, harmful,’’ lead author Jeffrey Swanson of Duke University said. ‘‘You and I might shout. These individuals break and smash things and get into physical fights, punch someone in the nose.’’
Usually encouraged and enabled by alcohol.
Angry people with guns are typically young or middle-aged men, according to Swanson’s research. They are likely to be married, and live in suburban areas. In a recent op-ed, Swanson and a coauthor point to Craig Stephen Hicks, a North Carolina man who ‘‘had frightened neighbors with his rages and had a cache of 14 firearms’’ and who shot three Muslim students earlier this year, as a quintessential example of an enraged gun owner.

Because it's another staged and scripted hoax to advance the agenda.
‘‘To have gun violence you need two things: a gun and a dangerous person,’’ Swanson said. ‘‘We can’t broadly limit legal access to guns, so we have to focus on the dangerous people.’’
But serious mental illness is only associated with a fraction of all violent crime in America.
Really? One would never have that impression after reading propaganda pre$$ day after day. WTF?
Swanson said the best available research shows that if you were to wave a magic wand and cure all serious mental illness in the United States, you would only decrease violent crime by about 4 or 5 percent.
Then why the big deal over this gun-grabbing study?
Maybe it is the prescription drug use responsible before those items went down the ma$$ media memory hole?
"Hicks, 46, appears to have been motivated by a long-running dispute over parking spaces at the Chapel Hill condominium complex where he lived. Hicks, who was unemployed and studying to become a paralegal, posted online that he was an atheist and a staunch advocate of the Second Amendment right to bear arms."
One wonders why Bo$ton isn't seeing more of that from what I've read regarding the parking.
