I personally think that some interpret the second amendment too literally. You have to keep in mind that it was written in a much different time and place. Its 2016 the United States has the worlds strongest military and competent law enforcement agencies that can respond to active shooter situations in minutes.
Lets be rational here we already have trained professionals to ensure that the public is safe we don't need civilians with minimal to no training everywhere with loaded guns.
Accidents happen and it breaks my heart when i see them on news children killing their friends or siblings or even their parents. How do you even explain to your child that their mother or father is dead because of them?
And then you have armed civilians trying to play hero it doesn't always have a happy ending I recall the incident in Wal-Mart where an armed civilian attempted to engage the guy who had just killed two Las Vegas police officers and was killed by his female accomplice. If he wouldn't have acted he would still be alive today, and that is my point we cant have civilians blinding running into situations that they have no training nor knowledge of.
If your against gun control that is fine, calm down the government isn't going to take your guns away and most likely wont make it harder for you to get new ones.
If your for gun control that is fine too, just dont expect changes to come quick or drastically.
I personally own a gun so Im not against guns i keep it at home for my personal protection, it never leaves my home. I purchased the gun because I lived in a rough neighborhood with frequent shootings and my home had been burglarized previously. I have moved but i kept the gun because bad things can happen anywhere and i want to be prepared.
I think we need to find a common ground in this debate and to me its a nation wide on ban assault rifles such as the used in this shooting. To me there is no rational or acceptable reason why a civilian needs to have a rifle in our society today. These weapons can inflict catastrophic damage in a matter of seconds as we have seen in recent history.
