State Representative Tom Brower vows to continue wielding his sledgehammer to smash abandoned shopping carts used by the homeless people in Waikiki, which is his district.  That's despite strong criticism. Marya Grambs, from Mental Health America of Hawaii, says what Brower is doing is unconscionable.  She accuses Brower of terrorizing people and modeling that it's okay to commit violence.  Brower estimates he has smashed 30 unmarked carts and returned six with logos to stores. He says critics don't live in the neighborhood where abandoned shopping carts are eyesores.
