There's no getting away from the fact that the Oregon shooting is the 994th mass gun shooting in the last three years. 300 have occurred this year. A mass shooting is classed as 4 or more people killed. Apparently there are many many more with for instance 3 killed and many with life changing injuries.
Whilst the organisation National Rifle Association exists, nothing will change, I fear. They bankroll the politicians and the gun industry funnel millions of $ to the NRA. They have huge influence over Washington and are a hugely wealthy organisation with immense power. They censor government data about gun crime, I don't think the public know half of it. They've blocked the renewal of the ban on assault and military weapons being available and have pushed for laws allowing the public to carry weapons openly. They and the gun industry are co-joined, so the NRA are there to protect the freedom of the gun industry to manufacture and sell any weapons they want to whoever they want.
So Kinder eggs are illegal in the US but a 26 year old can effortlessly buy 13 weapons and go and murder.
