February 2014: Ringling Bros. refuses to retire an elephant injured in a drive-by shooting.
Carol was shot in the neck by a drive-by shooter in Tupelo, Mississippi, in April, 2013. A popular petition calls for Ringling Bros. to allow the 39-year-old elephant to retire; the circus forces her back on the road less than a year later.
April 2014: Los Angeles bans the use of bullhooks, and Ringling Bros. says it will no longer perform in the city.
Past investigations have revealed elephants suffering from scars and open wounds after being struck with the sharp instruments.
July 2014: Ringling Bros. begins to cancel "elephant walks," which allow elephants to walk themselves from train stations to venues.
The walks are the only bit of exercise many of the animals get. Ringling Brothers say they're cancelling them because they're too difficult to organize; activists say it's because they're avoiding protesters.
