The director of the gun-control campaign Mayors Against Illegal Guns -- himself the son of a gun dealer -- told CBS hosts Rebecca Jarvis and Anthony Mason he was surprised by the tone National Rifle Association Executive Vice-President Wayne LaPierre took during his public statement Friday, the NRA's first since the Dec. 14 school shooting in Connecticut.

"The NRA is usually a pretty smart organization that calculates what it does very carefully, and it must have done so here," said Mark Glaze. "But I have to say, the talk that LaPierre gave -- which is not actually a press conference; questions were not allowed -- seemed so totally disconnected from the reality that the country that is rising up for action is actually facing that it's hard to understand what's going on in his head."

LaPierre has been roundly criticized after calling for schools across the country to install armed guards. Meanwhile, Glaze's group renewed its call on Friday for political leaders to deliver more stringent firearm regulations, releasing a video featuring television, movie and sports stars.

Glaze said that, while the NRA began as a place where people could fight for -- and win -- the right to have a firearm in their home, it has increasingly pushed for more extreme legislation, like the Michigan bill, ultimately vetoed by Gov. Rick Snyder (R), that would have allowed gun owners to carry concealed weapons in schools, daycare centers and hospitals.

He also took issue with LaPierre's statement on Friday that, "The only way to stop a bad guy with a gun is a good guy with a gun," saying the actual best deterrent is to keep guns out of the hands of "bad guys."
