In the South, the rifle-bearing eagle insignia of the National Rifle Association is seen everywhere, and support of the Second Amendment is as common a topic in country music as sweet tea and tailgates. The bond between the NRA and country music spurred the formation of an entire branch of the gun lobbying group, prompting a series of concerts and events sponsored by the organisation and headlined by country stars to bring the two entities together formally . But the Las Vegas mass shooting at a country music festival has rocked some of the most ardent supporters of gun rights. Country guitarist Caleb Keeter, who performed at the festival, wrote on Twitter, ‘I've been a proponent of the Second Amendment my entire life, until the events of last night. Now I cannot express how wrong I was.’
