Why did gandhi plead guilty

If you look at the slides from class connect our teachers gave us the answer to this and the two other questions

Mr. M. K. Gandhi, 53, Farmer and weaver by Profession, 'residing at Satyagraha Ashram, Sabarmati, Ahmedabad said: "I simply wish to state that when the proper time comes, I shall plead guilty so far as disaffection towards the Government is concerned. It is quite true that I am Editor of the Young India and that the articles read in my presence were written by me, and the proprietors and publishers had permitted me to control the whole policy of the paper." Mr. Shankarlal Banker, landed proprietor, Bombay, Second Accused stated that at the proper time he would plead guilty to the charge of having published the articles complained of. Charges were then framed on three counts under Section 124-A of the Indian Penal Code and the two Accused were committed to the Sessions. The case having been committed to the Sessions, Gandhiji was taken to the Sabarmati Jail where he was detained till the hearing which was to cosie off on March 18. At last the trial came off on Saturday the 18th March, 1922 before Mr. C. N. Broomfield I. C. S., District and Sessions Judge, Ahmedabad.
