Just a tad concerned when I see a person claiming to be a 16 year old asking for a good "carry" gun and a self defense gun. I would think if with his parents they would be doing the carrying and doing the defending. Also in answer to your question: yes youngsters who are planning such terrible events often do go online about it quite a while in advance. Their emails have been used as evidence against them in some cases.
Now don't get me wrong, I am not saying this youngster is doing anything wrong or is about to do anything wrong. For all I know he is a respectful, law abiding, great kid, but there are amber lights flashing because of his post. in other words, what I am saying is that the adults here should exercise some caution when responding to threads like this from minors especially when there is probably not a state in the USA that allows a 16 year old to carry a firearm for self defense purposes. Because of things like that I get that tingly feeling up my spine when someone claiming to be a 16 year old, and using the screen name of Gun crazy Jr, asks questions about such things. It makes me wonder and question what is a 16 year old doing with, or why is he wanting, a self defense "carry" gun. Now that could be because I am a cynic, or because I am a LEO, or maybe because I am a parent, or maybe better yet because I used to be a kid brought up in NYC - and not an angel at that; but whatever makes me ask - I don't think there is any harm in my wondering or my asking if all is right in Camelot tonight.
All the best,
