ALL police in the airports are armed. He was arrested by the airport police. Thus they were armed. Simples.
He told people to punch others. Being one of the "we just know" brigade (he doesn't, he lies) this is extra dangerous and encouraging violence for something that is not against the law.
Encouraging violence has NEVER been part of free speech, and never will. This is the correct way. Imagine being one of the people who receive death threats and threats of rape etc etc every day.
As I have spoken about before. Mr Linehan decided to "out" one of my friends as trans. My friend is not trans, but GL decided she was. She closed her social media down because of the hideous threats she received. Threats sent to her employer. Her children (including daughters) bullied in school for having a trans parent (again, not trans). Yes, other high profile anti trans activists jumped on his bandwagon, but he started it. And has still never apologised. He deleted the worst of the tweets, but not all.
He is no hero. He is no saviour of women. He does not care who he hurts in the crossfire.
