Lawyer Melissa Jean Beay has spoken to Penny Smith about America's firearms problems in the wake of five police officers being shot dead in Dallas.
The shooting happened after a protest against the shootings of Philando Castile in Minnesota and Alton Sterling in Louisiana, and marks the deadliest toll on US police officers since 9/11 in 2001.
"When I moved to New York and I had children of my own going over to play at other people's houses, it was a conversation in my house between myself and my husband whether or not that parent of that child owned any weapons," she said.
"Living in London for the last two years, has been a refreshing experience, because I can allow my 13 year-old to travel independently, to school without fear," she added. "I don't have fear that he's not going to come home."
