Another Mass Shooting -- Another Obama Address About Gun Violence

“We have to decide if this is the kind of country we want to be."

And with every mass shooting comes a very similar message from President Barack Obama.

"Our thoughts and prayers are not enough," Obama said after last year's shooting at Umpqua Community College in Roseburg, Oregon.

"This just doesn't happen in other countries," he said after the shooting at a Planned Parenthood in Colorado.

Early Sunday morning, Orlando, Florida joined the growing list of U.S. cities left shocked by violent massacres. At least 50 people were killed and 53 more injured in what police are calling the worst mass shooting in modern American history.

In a speech Sunday, Obama called the tragedy “a further reminder of how easy it is for someone to get their hands on a weapon that lets them shoot people in a school, or in a house of worship, or a movie theater, or in a nightclub.”

“We have to decide if this is the kind of country we want to be," he added. "To actively do nothing is a decision as well."

During the first 164 days of 2016, there have been 135 mass shootings in the U.S., according to Gun Violence Archive.

In the hours after the Orlando shooting, Sen. Chris Murphy (D-Conn.) blamed Congress for the slate of mass shootings, saying it has "become complicit in these murders by its total, unconscionable deafening silence."

"This doesn't have to happen," he said in a statement, "but this epidemic will continue without end if Congress continues to sit on its hands and do nothing – again."
