GL would have to demonstrate that he was put under such levels of harassment that it his reaction wasn't unreasonable and his response was proportionate that.
It's a tough line tbh, though this guy has done wonders in making that case.
Linehan is a hot head who hasn't been able to rein that in when needed. He bites when baited. This is a subject that needs cool heads and measured responses unfortunately.
What he's saying and what he's exposed is arguably in the public interest in many ways (yes the sexualised stuff which wasn't locked down behind privacy settings and was public even if it's grim).
That's why I'm open about him being guilty about this charge, but I do recognise it in the context of police failings and that he should never have been put in that position in the first place. So a conviction whilst correct could still be injustice because he hasn't been treated fairly and indicate a wider problem with the system at large.
It's also why I think other people who have not agreed with his approach in the past are still supportive of him despite his flaws.
