Self-identified political ideology is monotonically related to criminal conduct cross-sectionally and prospectively

From Political ideology predicts involvement in crime by John Paul Wright et al.  From the Abstract:

Political ideology represents an imperfect yet important indicator of a host of personality traits and cognitive preferences. These preferences, in turn, seemingly propel liberals and conservatives towards divergent life-course experiences. Criminal behavior represents one particular domain of conduct where differences rooted in political ideology may exist. Using a national dataset, we test whether and to what extent political ideology is predictive of self-reported criminal behavior. Our results show that self-identified political ideology is monotonically related to criminal conduct cross-sectionally and prospectively and that liberals self-report more criminal conduct than do conservatives. We discuss potential causal mechanisms relating political ideology to individual conduct.

Can't set much store by this for the usual reasons - it is sociology/psychology, no methods description, no effect size reported, political research is always at risk of confirmation bias, etc.

The only reason to focus on this is that an academic research team would most likely be oriented against this finding and because it fits so logically with the predicate definitions of progressive liberal and classical liberal (conservative).
