People may not have seen any change however there will still be blame chucked somewhere at someone else.

The police are already being accused of being slow for not having an armed team waiting for this to happen so they could jump on it.

Lots of people suffer from depression, should they all be watched carefully?
Not everyone that is depressed is receiving medical treatment for it so there is no one that can be accused of not informing someone else that a depressed person might do something really bad like this.

I suspect that doctors notes do not contain information such as if the person holds a firearms permit so if the docs did know of any depression they could not advise the police to remove the firearms pdq.

I am pretty sure that we won't ever know why he did this however it wont stop the media going over & over every little suggestion or theory and make it a prime time news article.
