US gun laws criticised after fresh shootings
Issued on: Modified:
This week, we ask if US gun control has failed again as a man with a history of mental health problems is able to buy a gun and use it to kill two people at a US movie theatre.
Also, we report from Colombia, where one of the country's most violent cities is fighting back against extreme violence, giving hope to the people there.
Finally, we take a closer look at the problem of horses running wild across America's West.
