If people want to be angry about something they should be angry at the people who let this freak out on the street knowing he had mental issues and chose not to do anything about it, instead of fixing the problem all people want to do is change this country into something they think is better, New Jersey and New York and Connecticut already have some of the strictest gun laws we have in this country and that didn't help to prevent this tragedy, most all of these horrific shootings that were committed by these people, these people were mentally unstable and in almost every case family members and friends new and they were diagnosed with some form of mental illness and the authorities were even notify but they all looked the other way,(( that is the problem)), , and if you look at all these horrific tragedies where they have mass shootings you will find that most all of them were committed in gun free zones where it was against the Law to have a weapon, so these murderers knew they would have no armed citizens against them so all the people are sitting ducks at the murderers Mercy, and anybody who thinks they can take the weapons away from murderers is living in a fantasy world those bad people will always find a way to get them, our own government even gives them out to the cartel in Mexico, we have had rifles and pistols with detachable magazines for as long as I can remember and I am 62 but we never had any problems like this until the last 10 or 15 years the weapons really have not changed that much, (but the people have) in this past 15 years or so, so much has changed in this country in a negative way from simple things like the food we eat is mostly chemicals today the doctors are handing out prescription drugs to our children like candy we no longer have enough jobs in this country for the people who live here creating a tremendous amount of stress on families the healthcare is a joke controlled by insurance companies who do not want to pay out for people who are mentally unstable forcing them to be out on the street to do these horrible crimes, today's children have been raised with incredible violence on TV and in the movies and videogames, our government knows this is happening but they do not do anything because they have no money they have spent it all on projects we don't need given it to other countries ,and our government knows any time a horrific tragedy like this happens they are one step closer to getting their way, there are so many ways to protect children in school but it seems nobody figured it out yet one simple door that separatesthe front lobby and office from the rest of the school that can be activated by a simple switch just like a sliding gate door you have in a prison, in most schools once you get inside the front entrance you have access to the entire school there should be a separation door between the children and the front office that is always closed and locked and can be locked remotely with a secondary lock and cannot be penetrated without a special key carried by law enforcement or fire department
