Is an tragedy a reason to push for gun control?: Kansas City Chiefs linebacker Jovan Belcher case

Costas' push for gun control seems to have triggered more calls among politicians.  From The Hill newspaper:

Democratic Rep. Diana DeGette (Colo.) on Monday slammed Congress for “doing nothing to protect our families and our society” from gun violence in the wake of a high-profile murder-suicide involving a National Football League player. 

“With the senseless tragedy in Kansas City this weekend, once again, gun violence finds its way onto our nation’s front pages; and once again we hear the same stale arguments from both sides of the political spectrum,” DeGette told The Hill in an email. “It’s clear these old arguments are doing nothing to protect our families and our society, so I urge our nation to come together and change the conversation.” . . .
