It's not just guns, it's America's culture of anger that is the killer
The murder of Alison Parker and Adam Ward was a postmodern nightmare. Vester Lee Flanagan II, who went by the name Bryce Williams, shot and killed his victims live on TV. He also filmed it himself and posted it on Twitter.
His motivations were a mix of the personal and political - Flanagan was a sad individual, who wallowed in imagined victimhood and wanted to start a race war on behalf of black people. This whole case tells us so much about the state of the modern American psyche. One thing it doesn't tell us very much about is gun control.
In the aftermath of shootings like these, there is always a push for gun control. That's understandable, I'm not unsympathetic. But - and this seems rather important - the Democrat proposals likely would not have denied Flanagan access to a gun.
