Since taking office in 2009, Barack Obama has had to respond to mass shootings in Fort Hood, Texas; Tucson, Arizona; Aurora, Colorado; Oak Creek, Wisconsin; Sandy Hook, Connecticut; Washington, DC;and Fort Hood, Texas (again). Several mass shootings, such as the 2012 massacre at Oikos University – a Christian school in Oakland, California – have gone almost unnoticed. Others, such as last week's shooting at a #BlackLivesMatter protest in Minneapolis, have gone unremarked on by the White House. But such is our new American normal. (It bears mentioning that Obama might have done more to curb gun violence, and unfettered access to guns, during his first year in office, when Democrats controlled both chambers of Congress.) As it is, here are the president's responses to mass shootings that took place in 2015:

'Nobody should have to worry about their security when gathering with their fellow believers. No one should ever have to fear for their safety when they go to pray.' – in April, after the mass shooting at a Jewish community center in Kansas

'Let’s be clear: At some point, we as a country will have to reckon with the fact that this type of mass violence does not happen in other advanced countries. It doesn’t happen in other places with this kind of frequency. And it is in our power to do something about it.' – in June, after the mass shooting at a black church in South Carolina

'Earlier this year, I answered a question in an interview by saying, “The United States of America is the one advanced nation on Earth in which we do not have sufficient common-sense gun-safety laws – even in the face of repeated mass killings.” And later that day, there was a mass shooting at a movie theatre in Lafayette, Louisiana. That day! Somehow this has become routine. The reporting is routine. My response here at this podium ends up being routine. The conversation in the aftermath of it. We've become numb to this.' – last month, after the mass shooting at a community college in Oregon

'This is not normal. We can’t let it become normal. If we truly care about this – if we’re going to offer up our thoughts and prayers again, for God knows how many times, with a truly clean conscience – then we have to do something about the easy accessibility of weapons of war on our streets to people who have no business wielding them. Period. Enough is enough.' – last week, after the mass shooting and standoff at a Planned Parenthood clinic in Colorado
