do you think we should be allowed to do homework in detention instead of punishment essays ?

A couple of weeks ago i had an after school detention as a punishment for non stop messing about in class, it lasted 1 hour 30 minutes, this did not include the 5 minutes to get to the detention room, once there we had to stand behind our desks while the detention teacher checked our school uniforms, we had to have our collars done up, ties neat and tidy and blazer done up, then the teacher took the register and gave out the work,which took another 10 minutes, i had to write a punishment essay on school rules and punishments, other students also were set essays , and some had to write lines, only then did the clock start for the 1 and a half hours, i got out of school 1 hour 50 minutes late, when i got home it was time for dinner, then straight into homework, so basically i had no freetime for myself, my question is if we could do homework in detention we could still have some freetime when we get home what do you think ?
