Once again The Post has gotten its facts wrong and shown its bias in reporting on an important piece of legislation that was passed overwhelmingly by the U.S. Senate ("S. 49: Help Your Local Police," editorial, July 9, and "Shot Down Senate- Style," editorial, July 11).

The Firearm Owners Protection Act of 1985 will not gut, but rather will strengthen, provisions of the Gun Control Act of 1968 and clarify ambiguous language that historically has been used to entrap and harass law-abiding gun owners and dealers.

Contrary to The Post's statements that interstate sales of firearms would lead to "quickie sales of handguns," the legislation would allow only law- abiding citizens to purchase guns in any state, provided that the sale comply with the laws of the purchaser's and seller's state. As far as the measessing of conceal- able weapons," Sen. James McClure's bill says nothto carry concealed firearms.

The proposed legislation would strengthen existing gun laws by 1) creating one class of seven persons prohibited from receiving, purchasing or possessing firearms -- current law has a different class for each category, and no one class is the same; 2) making it illegal for a private citizen to knowingly and willfully sell a gun to a felon -- current federal law prohibits only dealers from selling to crimi- nals; and 3) imposing a mandatory five-year prison sentence on those convicted of using or possessing a gun during the commission of a violent federal felony.

Most important, the McClure bill would redi- rect the efforts of enforcing agencies against the criminals who misuse guns and away from law- abiding gun owners and dealers, who have been the objects of 90 percent of enforcing agencies' investigations, the overwhelming majority of which were for technical violations of the gun laws.

The Firearms Owners Protection Act is not about easing gun control, but about correcting inadequacies, ambiguities and inconsistencies in the Gun Control Act of 1968.
