WASHINGTON -- President Barack Obama's proposals to tighten gun control rules may not accomplish his goal of keeping guns out of the hands of would-be criminals and those who aren't legally allowed to buy a weapon. In short, that's because the conditions he is changing are murkier than he made them out to be.

Some of Obama's comments and how they compare with the facts:

Obama: "A violent felon can buy the exact same weapon over the Internet with no background check, no questions asked."

The facts: It's not that straightforward. Federally licensed gun dealers are required by law to conduct background checks for gun purchases no matter where the sale takes place -- in a store, at a gun show or online. While private gun sales can be conducted over the Internet, if the sale involves people in different states, a licensed gun dealer in the state where the gun is going still has to be involved in the transfer.

Regardless of the seller, it is illegal for convicted felons to buy or possess guns unless they have had their rights restored.

Obama: "We're going to require firearms dealers to report more lost or stolen guns on a timely basis."

The facts: The effect of this is unclear because the government already requires gun dealers to report all lost or stolen guns within 48 hours of discovering they are missing.

Obama: "Anybody in the business of selling firearms must get a license and conduct background checks, or be subject to criminal prosecutions. It doesn't matter whether you're doing it over the Internet or at a gun show. It's not where you do it, but what you do."

The facts: "In the business" is the key condition for coming under this requirement, and the definition may have a lot of wiggle room. Federal law defines people who "repetitively buy and sell firearms with the principal motive of making a profit" as being "engaged in the business" of selling guns and requires them to be licensed. The license process includes a $200 application fee and a criminal background check. People who occasionally sell guns from their personal collections don't have to apply.

The law does not specify how many guns a person has to sell to be considered "engaged in the business" of selling guns, and neither did Obama. His new guidance defines a dealer as one whose "principal motive" is profit.
