President Barack Obama plans to make smart gun technology a primary part of his push to control firearms, but an expert warns that the new high-tech weaponry poses a danger to constitutional rights—and he’s not talking about the Second Amendment.
In April, Obama posed the question, “If we can set it up so you can’t unlock your phone unless you’ve got the right fingerprint, why can’t we do the same thing for our guns?” 



Obama released a presidential memorandum requiring three departments to push smart gun research—the departments of Justice, Homeland Security, and Defense. The memo also entices the industry to manufacture those devices by offering to provide funding for research. But applying the standards of phones to guns could create significant problems said Joseph Greenlee, a Second Amendment lawyer from Frisco, Colorado, and a member of the Federalist Society for Law and Public Policy Studies.
Smart guns are firearms that incorporate a safety feature that would allow only authorized users to fire it. This would include fingerprints to unlock the gun, or the use of a biometric sensor that detects the grip and hand size of the rightful user.
