In response to Leah Latimer's article "P.G. Student Suspension Rate Criticized" {Metro, Sept. 11}, as a black teacher in Prince George's County, I uphold Superintendent John Murphy's stringent discipline policy. Rules are for everyone to follow regardless of color. If more black youngsters see fit to ignore those rules, they must be made to face the consequences. That's life!

Continued classroom disruption, insubordination and disrespect rob the students who do want to learn of valuable teaching time. Some may find P.G.'s suspension rate objectionable; however, they should substitute as a teacher one day and see firsthand what really goes on in our schools.

One problem is overcrowded classrooms. In a class of 32 or more, discipline takes precedence over subject matter. If a student does not come from a well-regulated family structure that emphasizes cooperation, responsibility and respect, he will not be able to cope with the almost knee-to-knee closeness.

Another problem stems from a total lack of morality, decency or sociability. Some students are angry and inept; therefore, they disrupt. Fighting is a way of life. Teachers are cursed, defamed and ignored. When one confronts a student who is using vulgar terms, one is met with utter contempt, hostility and defiance. Yet, Mr. Richard Brown, executive director of the county branch of the NAACP, sees suspensions as a "sad indictment on the superintendent of schools and the Board of Education."

On the contrary, these suspensions are a sad indictment on the parents of these student offenders. True, the role of the teacher has expanded. However, the teaching of good manners, respect and regard for others should be the domain of the home during the formative years of a youngster's life, not of the 11th grade that I teach. Put the blame for these suspensions where it must assuredly rest -- in the home. GERALDINE F. WILLIAMS Fort Washington
