I have tried to find a word that can fully describe my emotions regarding the actions of Fairfax police in the arrest of Mrs. Retha Morgan {"Police Infiltrate Vienna Party," front page, June 13}. Appalled, flabbergasted -- none seems to describe my feelings.

This wonderful country of ours is slowly turning into a self-righteous reactionary state. Deregulation is the buzz word for industry, and yet regulation seems to be the buzz word for individual rights. We are being tested for drugs, smoking is practically banned from all public places, and now we cannot even hold a party for our children (or for ourselves) without the police trespassing on our property and snooping around to find something to infringe on our rights.

No, I do not believe that we should abuse our bodies with drugs, alcohol or smoke. But I firmly believe that we as Americans have our rights, and we must preserve them. If you are driving under the influence of alcohol, then your license should be revoked. If you use illegal drugs, the law dictates that you should be punished. If you smoke where prohibited, you must pay the consequences. But it is simply beyond belief in this free nation that police can be permitted to sneak onto your property during a party.

Reporters can stake out a person's house to cause the demise of a political candidate. Now the police can take extraordinary measures in the name of law and order. YOLANDA WOLF Alexandria

The editorial "Bashbusters in Fairfax" {June 16} accuses the Fairfax police of "outrageous overkill." May I suggest that The Post's views could be termed even more of an outrageous overkill and absolutely one-sided? And though The Post states that "precise details of the evening are in sharp dispute," it does not hesitate to act as judge and jury.

I would like to make a few points: First, was it wise of the hosts to invite more than 600 students to a residential neighborhood for a party? The Post writes ". . . here was a couple who tried to have a celebration for their son and his friends." But if everyone in the senior class is this son's friend, he must be a very popular fellow.

Second, when the hosts discovered that some of those present were breaking the law, why did they not call the whole thing off? The police, I am certain, would have been happy to cooperate. Furthermore, posting signs to discourage drinking, as the hosts did, is not enough. If signs were truly effective, no one would ever break the speed limit.

Third, when someone provides drivers who will not drink to act as chauffeurs for those who may drink, does it not give implicit permission to drink?

And to the unnamed Montgomery County police official who commented, "Personally, I'm a little shocked. We've got better things to do," I would say, "Like what? Drinking coffee at 7-Eleven? PHILIP DOHERTY Burke
