On Monday, President Obama announced a series of small but significant changes to federal gun regulations. One of the key reforms will require more gun sellers to obtain licenses, which will mean more background checks in private transactions and at gun shows since, under current law, all licensed sellers are required to perform background checks. Other provisions include hiring more than 230 additional people to process background checks, increasing efforts to track lost or stolen guns, and designating $500 million in federal dollars to increase access to mental healthcare.
There are other changes involving domestic violence outreach and ensuring states are actually providing records to the background check system. That said, with the exception of expanding what it means to be "in the business of selling firearms," Obama's executive action is mostly about better enforcing existing laws and allocating additional resources to staffing up current enforcement mechanisms.
