Here's a contrarian point of view. Yes and thank God there were no terrorist incidents last night, however, as one looks at the sea of security that blanketed the big celebrations, has anyone considered the mounting cost of becoming fortress America? Security, for all its good, is and will always be an overhead cost that becomes unsustainable when funding drys up.
Personally, I consider the odds of becoming a victim, shrug it off, and go about my business.
