Your recent editorial on childhood obesity calls on the state legislature to ban school vending machines that sell junk food ("Easy call in obesity fight," Aug. 23). But why every perceived problem demands a legislative solution is beyond me.

Don't school principals already have the authority to determine what is sold in their school's vending machines? And if principals don't, what about county superintendents and school boards?

If none of these officials have the authority to determine what will be sold in school vending machines, or even whether such machines should be allowed in the schools, what have we come to?

If The Sun is so keen on passing more legislation, here's a suggestion: First, all new legislation must have a sunset provision, so that its wisdom can be re-evaluated after five years or so.

Second, sponsors of new legislation must include as part of their proposal a provision to repeal some other law that is currently on the books. I suspect it would take at least 50 years to weed out just the inane or antiquated laws that are no longer relevant but remain on the books.

Finally, enact a law that applies the first two principles to all new rules adopted by the state's regulatory agencies.
