First, you know, you really gotta feel sorry for Ron. He just digs his hole deeper and deeper and deeper with every one of his posts.
Ron, how many of the incidents to which you linked took place at an airport? I'll give you a hint: the answer is a number less than 1.
Second, each and every article to which you link just reinforces the need to screening each and every person who enters the secure area of an airport. Each of the suicide bombers was just a seemingly normal guy or gal, with the possible exception of the Down syndrome child, who never drew attention to him or herself - probably not a great deal unlike ramp workers, food service workers, TSA screeners. That's why EVERYONE who enters the "secure" area needs to be screened. Otherwise, the area is not secure.
Ron, do yourself a big favor. Stop posting. Or do you like being made to look the fool?
