As America comes to terms with the latest gun tragedy, will the nations's shock be enough to bring about a change in the law?
TV reporter Alison Parker and cameraman Adam Ward were shot dead live on television as they broadcast into a local news station's morning show in the U.S. state of Virginia last week.
The gunman, Vester Flanagan, was a disgruntled former colleague.

It's the shooting that's shocked America. But in this Virginia gun shop it's business as usual. Co-owner, Joshua Karrasch believes there are ways of making gun ownership safer.
"I feel education, training , maybe we could even start talking about universal background checks as good starting points but the bottom line is firearms are here and we can't ban them"
But Alison Parker's grief-stricken parents say they will not be cowed by the pro-gun lobby – vowing not to rest until the law is changed. It is a tall order. The most recent research says there are 300 milllion guns in the USA and nearly a third of adults owns one. And according to website, gun archive dot org 8 thousand seven hundred people have been killed by guns in the US so far this year. But figures like that are still not enough to force a change in gun legislation. Campaigner Lori Haas, whose daughter was shot and injured in the Virginia Tech shooting in 2007, is hoping the latest incident may shock America into reexamining gun control.
"I think seeing this live on TV, knowing that the shooter filmed it from his perspective is just galling and upsetting to so many people, I'm expecting we'll see an increase in support for better regulations."
President Obama wants change too. In an interview with ABC News on the day of the shooting he said he was heartbroken.
"It breaks my heart every time you read about or hear about these kinds of incidents. What we know is the number of people who die from gun related incidents around this country dwarfs any deaths through terrorism."
But despite presidential support past experience suggest it's unlikely much will change - while the pro-gun lobby continues to wield huge influence and the Republicans remain in control of the US Congress. Kate Fisher, Washington>
