Khairi Saadallah, 26, pled guilty to three murders and three attempted murders
Saadallah launched a two-minute stabbing spree in Forbury Gardens, Reading
James Furlong, 36, David Wails, 49, and Joseph Ritchie-Bennett, 39, were killed
Crown is seeking a whole life order meaning he would never be released
But his defence suggest life imprisonment starting at 30 years because lack of serious premeditation, and fleeting commitment to Islamist extremism
