The Life story caused something of a tumult around the country (Yates), and some authors have asserted that the AMA subsequently released a press statement disclaiming involvement in the Hollister event, stating that 99% of motorcyclists are good, decent, law-abiding citizens, and that the AMA's ranks of motorcycle clubs were not involved in the debacle (e.g., Reynolds, Thompson). The American Motorcyclist Association says it has no record of ever releasing such as statement. Tom Lindsay, the AMA's Public Information Director, said 'We [the American Motorcyclist Association] acknowledge that the term 'one-percenter' has long been (and likely will continue to be) attributed to the American Motorcyclist Association, but we've been unable to attribute its original use to an AMA official or published statement—so it's apocryphal.'
