Editor: I would like to respond to your editorial, ''High Noon in Towson,'' by supporting Sheriff Norman Pepersack's request for full law enforcement capability.
It is true that Baltimore County has a professional police force of 1,500 sworn officers and Baltimore County also is served by a smaller group of professional officers belonging to the Maryland State Police.
Law enforcement efforts would be enhanced by granting Sheriff Pepersack's request.
The State Police and Baltimore County Police have a signed contract, which reduces the possibility of duplication of effort. I see no reason why the Baltimore County sheriff's office cannot share in law enforcement activities. I am sure there is sufficient work to keep all three agencies busy.
Editorials such as ''High Noon in Towson'' only create more tension between the sheriff's office and the county police, rather than helping the situation. I would suggest that you attempt to unite the two outstanding law enforcement agencies rather than divide.

Editor: Lou Ferrara (news story, Dec. 30) wrote about a book that offers advice to university students on earning an A by cheating.
Your correspondent provided the name and address of the author, as well as the title of the book and its cost. The tone of the article was uncritical of the criminal activity being recommended.
When American students are generally persuaded that sleazy methods are acceptable, and that only ''squares'' are honest, the United States will have become a third-rate nation. University diplomas will have no value.

Enough is Enough
Editor: In your Jan. 3 editorial, ''El Salvador's Happy New Year,'' you state: ''For 12 long years, the United States tried to promote democracy in El Salvador by arming and training a military committed to an authoritarian, elitist, feudal system.'' Twelve years later, the question remains -- just what does an ''authoritarian, elitist, feudal system'' have to do with democracy?
I believe that the U.S. government has achieved a different mission -- keeping the Marxist FMLN out of power at all costs -- even if that meant continuing to fund the military whose death squads had killed Salvadoran civilians and American Jesuits.
I applaud your call for the Salvadoran military to be ''isolated and cut off from money and armaments'' and I submit that the only way to achieve that is to stop all U.S. aid. I say ''enough.'
Let's demonstrate our resolve. The Cold War is over and our federal tax dollars will be better spent at home on American citizens who are unemployed, homeless or without health insurance.

Editor: Compassion should be extended to, among others, editorial writers of The Sun, who almost daily must meet a deadline. That most of the product is readable, does not defy common sense and is only rarely absurd is highly commendable. At times it reaches the stars.
The Jan. 2 editorial, ''America 1992,'' in The Sun was in the finest tradition.
Uncommonly prescient, succinctly written, it searches through the enormous complexities of life in the United States to suggest that the American people are mostly ''. . . obsessed with the internal failings of the most prosperous and successful polyglot society in all of human history. Its own.''
Its prediction is: ''If the New Year accomplishes anything, it will be to make American society more caring, more tolerant and more determined than ever to achieve great things through self-reform.''
In The Sun, Maryland has something valuable. Let's hold on to it!

Editor: Mark Cooper's recent Opinion * Commentary article, ''The Baby Bells are Loose; Expect More Chaos,'' is another scare tactic aimed at turning good news into bad. The fact is,the nation's highest courts have granted the Bell companies freedom to start bringing useful, affordable Information Age services to the American public.
Because the Consumer Federation of America chooses to defy other consumer groups and oppose every new venture the Bell companies undertake, they oppose these court decisions also.
Cooper's claim that the Bell companies have overcharged customers and applied the earnings to unregulated businesses is unsubstantiated and completely false. In Bell Atlantic's territory, local telephone rates have actually gone down, while customers have had access to an increasing variety of new services.
Voice mail, for instance, has attracted 350,000 customers in Bell Atlantic's region alone-- despite the consumer Federation of America's assurances that consumers didn't want or need these services from their local phone company .
