What police DON'T want you to know about the Dezi Freeman manhunt
A former Australian Federal Police boss has shared insight into the manhunt for alleged cop killer Dezi Freeman and why police have been tight-lipped about specific operational details.
The Australian Defence Force has been called in to join the marathon hunt as efforts to track down the fugitive ramp up.
Former Australian Federal Police detective superintendent David Craig has detailed how military involvement will assist tracking Freeman down.
'The military have access to technologies that aren't available to the civilian population and aren't made public,' he told Sunrise on Thursday.
'I don't feel comfortable in listing some of those, but it is another level.
'The operation will still be led by the Victorian Police, who are doing a very good job with this.
'They just need some additional technical support, and in other cases similar to this, where the military have not been involved, they've gone on unresolved in these manhunts.'
