I’m sure in his mind it makes sense.

WASHINGTON (AP) — President Barack Obama reached out to an online audience Thursday, taking questions on deadly subjects like drones and gun violence while also musing about the anachronism of pennies and the “chill” factor in Hawaii. [...]

Obama also defended his proposals to ban certain weapons and bullet magazines and expand background checks on gun buyers.

“We already have some restrictions.” He said. “We can’t purchase a grenade launcher from a store, although there may be some folks who want to buy those. And the reason is that we think that on balance the second amendment does not automatically assume that any weapon that’s available you can automatically purchase.”
