Sure but as Obama said America is the only society that has these kind of mass killings on a regular basis - it has happened now about 15 times since he took ofiice.
It's one thing to challenge statistics but it can be overdone just as global warming is being denied by unscientic arguments.
Australia brought in gun control and have drastically reduced gun killings. Why fight success?
We no longer live in a society where guns are required. Yes of course there will be exceptions and that is why London police used to keep weapons at the police stations but the police were not walking around carrying guns.
And so there is nothing anyone can say now that will convince me guns are required and the sooner we get rid of them the healthier and safer society we will all be.
So to summarise:
1 - Gun control is not complicated
2 - Science has shown gun control is effective in reducing gun violence
3 - 21st century society no longer requires guns
4 - Gun control is long overdue
5 - We need effective and courageous polical leaders to effect the change.
