According to E! Online, Britney Spears, Avril Lavrigne and other celebrities have submitted their written testimony in support of the bill.
The act's introduction begins (via The San Francisco Chronicle):
The legislature finds that Hawai‘i is home to many celebrities, particularly on Maui, who are subjected to harassment from photographers and reporters seeking photographs and news stories. The privacy of these celebrities endure unwarranted invasion into their personal lives. Although their celebrity status may justify a lower expectation of privacy, the legislature finds that sometimes the paparazzi go too far to disturb the peace and tranquility afforded celebrities who escape to Hawai‘i for a quiet life.
Hawaii Gov. Neil Abercrombie said he supports the bill but wanted to change some of its language, the Daily Mail reported.
The Steven Tyler Act's opponents, including ACLU attorney Laurie Temple and the National Press Photographers Association, believe it curbs photographers' First Amendment rights.
