Families call on governments to act as loved ones fall into extremism

When Emily's teenage son became withdrawn, she never imagined he had secretly joined Australia's most prominent Neo-Nazi group. Now, she and other families are speaking out for the first time, revealing to reporter Avani Dias the painful reality of radicalisation and the struggle to get help. 

Australian authorities are urging families to report extremist behaviour and engage in early intervention programs " but many say the system is failing them. A serving police officer has now broken ranks, backing these families and warning that current efforts aren't working. 

This Four Corners investigation exposes the growing threat of homegrown extremism and the desperate calls for stronger action.  

Leaving Hate, reported by Avani Dias, goes to air on Monday 17 February at 8.30pm on ABC TV and ABC iview. See more at abc.net.au/news and on ABC News social media platforms.
