Channel 4 for the next week have allowed this to be viewed globally or so I am told.
In short the documentary collates footage and testimony that suggests the Sri Lankan government directly fired on Tamil civilians during the last stages of the civil war in 2008-2009, executed bound prisoners, committed sexual atrocities, even using GPS locations given to them by the Red Cross to shell hospitals they were supposed to avoid! The silence on Sri Lanka compared to say, Libya is defeaning.
What can be done?
Warning: It's a very very bleak documentary, with videos of people being shot
