LONDON School of Economics lecturer and campaigner Lisa McKenzie said she was still “angry” after being found not guilty of public order charges brought by the Metropolitan Police in a trial that ended yesterday.

At Stratford magistrates’ court in east London, a judge found her not guilty and expressed “concern” over Dr McKenzie’s profiling by the police.

The former Class War parliamentary candidate was arrested in April and charged with three public order offences, including one of “criminal damage” after she allegedly glued a sticker to a window.

Yesterday, the judge allowed the original charges against her to be swapped for one of joint enterprise, by which the actions of others would be imputed to Dr McKenzie as well.

But the court did not find enough evidence to convict her of any of the alleged crimes.

Under questioning, one of the testifying officers admitted that Dr McKenzie was being profiled by the police before her arrest.

Speaking to the Star, Dr McKenzie said: “I’m really angry. I’m angry that the Crown Prosecution wasted taxpayers’ money.

“I am really angry that they wasted almost a year of my life.

“I think the state really struggles with me because I identify as a working-class woman and I am an academic and I work at the LSE. So actually I think this has been a witch-hunt against me.”

Asked whether she felt her case had sent a precedent, the sociology lecturer added: “I think this could happen again.

“The anger that is coming from the grassroots, the inequalities and the unfairness of what is happening to working-class people all over Britain — I honestly do believe that there’s a class war.”
