I believe everyone is jumping to conclusion that the young man/boy was against the government position on gun control. If you read his statement-
‘‘I said, ‘I have a gun in my pocket right now, how would the government know about it?’,’’ Brendon said. ‘‘I was trying to show how unsafe schools could be, and how anyone could just walk in with a gun, and no one would know.’’
You will realize that that statement could have been used as an arguement for gun control as in the policy of no guns at all.
