In a hearing at the Connecticut state capitol yesterday, pro-gun demonstrators actually heckled the father of a 6-year old boy killed in the Newtown school massacre.

There are no words.

The sometimes boisterous public hearing — after nearly four hours of testimony from State Police, parents of slain Newtown first-graders and city mayors — seemed dominated by gun owners, who railed at more than 90 proposed bills.

“The Second Amendment!” was shouted a couple of times by as many as a dozen gun enthusiasts in the meeting room as Neil Heslin, holding a photo of his slain 6-year-old son, Jesse Lewis, asked why Bushmaster assault-style weapons are allowed to be sold in the state.

“There are a lot of things that should be changed to prevent what happened,” said Heslin, who said he grew up using guns and was undisturbed by the interruption of his testimony.

“That wasn’t just a killing, it was a massacre,” said Heslin, who recalled dropping off his son at Sandy Hook Elementary school shortly before Lanza opened fire. “I just hope some good can come out of this.”
