I too was horrified at the news.  I too pray for the families.  Wake up call America!

The solution:  I have no idea. 

I agree with Quest that more laws are not the answer.  It is too late to control guns.  There are too many out there now and control means "no one but the criminal will have them" 

I agree with D_A_M in that if a gun was not handy then it would be bombs constructed via instructions on the web.  Would gun control laws have stopped the massacres in Africa by warring Tutsi (sp)?  Machetti's were the weapon of choice.  Or would the Iraqi parliment's passing of a law making it illegal for a citizen to have a gun stop the suicide bombers? 

When political machines start grinding in these here United States the results are too often over complicated as to appease every money contributing pact possible and keep the campaign money coming in.  At some point the politicians have to make a choice of the source of money, right wing or left wing.  Then they start compromising the bill so not to cut their buddy completely off his/her funds and support.  The result is usually wordy, non-enforceable, illegal (because of other laws or Constitution) and winds up in courts forever.  Look at the snafu about illegal aliens in USA with the key word "illegal".   We can't figure out how or why we should give "illegals" social security and other benefits.  I love my country but it has big problems.

Is this now the "Land of the free... and run amuck"? 

BUT... the problem is not in US only.  Human race is devolving.  All humans have choices and all choices have consequences.  I am so proud of the couple here that have acknowedge affliction of clinical depression.  I am so proud that they realized the consequences of not admitting  their medical and physcological needs.  Bravo, for your choices. 

IF it was known by someone that depression was apparent in the gunman's life previously then I venture the assumption that it was not kept a secret diagnosis from the young man himself.  He made choices.

Willie steps off soap box, realizing this is not a blog site. 

PS  I do not own a handgun.  Hand guns are designed with one purpose in mind, to shot people.  I have a shot gun that belonged to my grandfather.
