Varying training and hiring standards across the state. The sometimes too thin of a line between cop and criminal. Being surrounded by the worst in society day after day. Standards for reserve or part-time officers. Bad luck.
And I wouldn't look at it as 6 times worse than license holders, look at it as they're at least 6 or 7 times less likely than the general population to commit crimes. License holders are just 12 ~ 14 times less likely.
