ejected from a meeting in Synod Hall, Edinburgh, where Sir Rufus Isaacs was speaking, Moorhead returned to attack the male lecturer from Broughton School at his work, with a dog whip to attack him in return for having ejected her. Letters to the press objected at the physical violence to eject women who were simply wanting to question speakers, and others from the crowds who cheered on and supported the violence. She was arrested for this attack under her own name, and was fined £1, which was paid, so Moorhead never went to prison for her action. The next month, 29 November 1912, Moorhead (in the name of 'Mary Humphrys') and Fanny Parker, whom she had befriended in prison before, and Olive Wharry (under the name of 'Joyce Locke') and Emily Davison (under the name of 'Mary Brown') along with minister's daughter Mary Pollock Grant (under the name of 'Marian Pollock') planned that some women may be able to get into the Liberal Association meeting in Aberdeen where Chancellor of the Exchequer Lloyd George was to be speaking. Moorhead and Davison were to attack outside but went for the wrong person, and Moorhead broke a car window, but all of the group were arrested. Again Moorhead conducted her own defence including requesting that Lloyd George be called as a witness. Of course this did not happen, and again she was fined (40 shillings) or to be imprisoned (ten days) for damage to property which she chose. This was the first time she went on a hunger strike, but with the others was released early as the fines had been paid, anonymously. Moorhead wrote to the press (The Scotsman) complaining about prison conditions on remand and in the Aberdeen gaol which led to questions to the Secretary of State in Parliament, as the complaint was about pre-trial behaviour by the police. She had a reputation for wrecking police cells, and carrying out several arson attacks. Moorhead had thrown cayenne pepper at a police constable at an event where Prime Minister Asquith was due to speak, and was taken to Methil and then Dundee prison, where she caused an amount of damage by breaking windows. Early in 1913, she tried to write to Arabella Scott who lived at 88 Marchmont Road, Edinburgh about an incident of an amorous approach by an inebriated prison doctor, which she feared would be used as propaganda.
