No one wants the punishments, so it might be why such quotas still exist in certain parts of the country. On a positive note, this practice is under large scrutiny and more states are starting to implement the ban on it.
Illinois banned ticket quotas in 2014.
Arizona passed a legislation in 2015, but the governor vetoed it.
California (L.A.) paid two different settlements for lawsuits alleging that performance of officers was being evaluated based on if they met the ticket quota. $2 million was paid out in 2009 and $6 million in 2013.
