Lower Township - If guns are so bad, then why do they send in a hundred people with guns to stop a bad guy with a gun? Why do all the politicians have Armed guards? Why does Nancy Pelosi have armed security guards walking her house grounds? Why does Obama and his family have armed personnel around all the time or any ex-President for that matter. Why do big banks have armed guards? Why do military bases have armed guards? Do you really think the bad old gun is gonna go shoot some of them by itself?
Seems to me the gun isn't an issue at all, maybe it's the people who pull the triggers.
