If assaulted by a security guard on video, the defence of self defense is a full exculpatory defence before the Court when you can see on the evidence that reasonable force was used. If set for trial, the Court will decide. This is not a matter worthy of a trial. With the evidence on camera, there is no case to answer by the defendant. The facts are agreed to by the Crown and the Accused. The Security Guard is also charged since he has no licence in law to use physical force or detain members of the public.
