Keeping kids safe

Detroit News reported today on measures area schools are taking to step up security:

Detroit Public Schools has some of the most extreme safety measures in place. Metal detectors and security guards are standard at district high schools. The district used to search students' clothing, backpacks and cars, but agreed to stop unless they had reasonable suspicion under a 2006 court order. The American Civil Liberties Union is now suing the district, alleging it violated that order at Mumford High School.

District officials, who couldn't be reached Thursday, have said they did increase security at Mumford because of ongoing problems there but denied they've conducted unconstitutional mass searches.

What do you think? How can childrens' safety be ensured without making them feel they are entering a prison?
