While there has been a Federal law on the books for more than 20 years that prohibits the sale of firearms to felons, fugitives, drug addicts and the mentally ill, it has no enforcement mechanism and basically works on the honor system, with the purchaser filling out a statement that the gun dealer sticks in a drawer.

The Brady bill would require the handgun dealer to provide a copy of the prospective purchaser's sworn statement to local law enforcement authorities so that background checks could be made. Based upon the evidence in states that already have handgun purchase waiting periods, this bill -- on a nationwide scale -- can't help but stop thousands of illegal handgun purchases.

And, since many handguns are acquired in the heat of passion (to settle a quarrel, for example) or at times of depression brought on by potential suicide, the Brady bill would provide a cooling-off period that would certainly have the effect of reducing the number of handgun deaths.

Critics claim that "waiting period" legislation in the states that have it doesn't work, that criminals just go to nearby states that lack such laws to buy their weapons. True enough, and all the more reason to have a Federal law that fills the gaps. While the Brady bill would not apply to states that already have waiting periods of at least seven days or that already require background checks, it would automatically cover the states that don't. The effect would be a uniform standard across the country.

Even with the current gaps among states, those that have waiting periods report some success. California, which has a 15-day waiting period that I supported and signed into law while Governor, stopped nearly 1,800 prohibited handgun sales in 1989. New Jersey has had a permit-to-purchase system for more than two decades. During that time, according to the state police, more than 10,000 convicted felons have been caught trying to buy handguns.

Every year, an average of 9,200 Americans are murdered by handguns, according to Department of Justice statistics. This does not include suicides or the tens of thousands of robberies, rapes and assaults committed with handguns.

This level of violence must be stopped. Sarah and Jim Brady are working hard to do that, and I say more power to them. If the passage of the Brady bill were to result in a reduction of only 10 or 15 percent of those numbers (and it could be a good deal greater), it would be well worth making it the law of the land.

And there would be a lot fewer families facing anniversaries such as the Bradys, Delahantys, McCarthys and Reagans face every March 30.
