An anonymous reader writes: Today U.S. President Barack Obama rolled out a set of executive actions aimed at reducing gun violence. The most controversial of the provisions requires licenses for those who sell guns at gun shows and on the internet, and forces background checks on buyers. There are also a number of measures dedicated to making background checks more foolproof and universal. Less controversial but more on-topic for Slashdot is that Obama is requiring the departments of Defense, Justice, and Homeland Security to investigate smart gun technology. This can include RFID chips, fingerprint scanners, and other bits of technology. Their goal will be to "explore potential ways to further its use and development to more broadly improve gun safety." The new gun measures include a proposal for a $500 million investment into providing care for people with serious mental illnesses.
