Cop curses at kid dialing 911

You’d seriously think I hated cops the way I bash them on this site. But truth be told, I respect the job that some of them do and do well. My problem is if you are going to hire someone for a job like that, why aren’t they the best and the brightest of people? Cops are usually the line between life and death, so why would you have an imbecile on the force that can’t make great (or at least good or at least not bad!) judgments all the time? Maybe they need to put cops on a rotational block and have them work only 9 months of the year. That way they never get fully burnt out and make stupid choices.
