The Post was right to give front-page publicity {Nov. 17} to the utterly indefensible decision of the Montgomery County prosecutor to plea bargain the killing of bicyclist Jo Anne Royle by a drunken motorist down to a one-year jail term.

This errant result is further concrete proof that the mothers and others against drunk drivers have made but paltry inroads in their efforts to rework the attitudes of the criminal justice system toward drunk drivers. It does not suffice for juries to be sensitized to the legitimate demands of the outraged victims of drunk drivers. Nor is it enough to reorient the sentencing structure by giving victims a right to be heard on the sentencing disposition. Prosecutors, too, have some learning to do in their expedient use of plea bargaining in homicides related to drunk driving.

So long as prosecutors have essentially unreviewable discretion to unclutter their dockets through plea bargaining, drunk drivers' victims will never see the violators answerable in court. Legislators must awaken to the need to put a break on prosecutorial discretion to "deal" in these cases. A number of controls can be proposed. Appellate review of the prosecutor's decision is one of them. Another would be to deprive the prosecutor of such discretion entirely, forcing the issue to be brought to trial. Minimally, prosecutors could be compelled to solicit and to take into consideration the wishes of the victim's kin before a plea bargain is struck.

Whatever remedial action is taken, it should be chosen with the clear understanding that justice is not done unless it is seen to be done. Plea-bargained justice in drunk-driving homicides is closet justice and, as such, is none at all.

I wish to thank both Judge William Miller and Assistant State's Attorney Ann Harrington for offering to the masses yet another hunting season. There is a duck season, a deer season and -- now -- a bicyclist season. We gratefully owe this new season to one David Henry, who by his bold actions proved that intoxicated individuals with "traces" of drugs in their blood are allowed to kill human beings, as long as the human is riding a bicycle.

All right! All of you out there -- finish that bottle of bourbon, snort that cocaine, go out and get yourself a human on a bicycle. And, remember, no prize unless you bring your trophy home on the hood of your car. LUCI BORRIS Annandale
