There have been 7 Portland police officers arrested for various acts including felony assault since the first of the year. A spokesman for the department stated, "It's a big organization..." and went on to justify the number by implying that it's a relatively small percentage. I work for a company with about 3000 employees and I doubt that a similar percentage of them were arrested this year, not even close. My take on it is that people with issues have always been drawn to enforcement work, but there are usually controls in place that weed them out of candidate pool. Apparently, those controls are somewhat lacking in Portand over the last decade or so.
