Easy availability of guns is at the root of USA's mass shootings
Once again, we are in a period of mourning for innocent lives, this time in the attack on the Pulse nightclub in Orlando, Florida - the latest gun massacre in the US.
Once again, there are various reactions, much as before: genuine sorrow, politicians' promises, crocodile tears and much glee by gun dealers at the prospect of sales rocketing again at the threat of gun-control measures.
The main problem is the easy availability of guns. This is due to America's gun culture, which, historically, has been sustained by many groupings and interests: the National Rifle Association (NRA), the Ku Klux Klan, the Black Power movement etc.
