A Mad World

Shooting in Arizona results in 5 dead & a US Congresswoman shot in the head. Dreadful as it looks as though the 22-year-old male gunman was targeting the politician because of her Democratic liberal views. He is supposedly a troubled young man, a loner etc. Why did he have or have access to guns? Why can't America take a look at their gun laws and realise that they are wrong. The right of every citizen to carry arms might have been valid many years ago when defending their homesteads against enemies or animals but it simply doesn't make sense in the 21st century.
