> I doubt judgement is heavily impaired at 0.05 BAC. That is at or below the legal limit to drive a car.

0.05% BAC will result in a DUI in many countries. Regardless, any impairment on a job where you're doing things guaranteed to summon the cops is a very bad idea.

BAC also declines linearly over time. I doubt (hope?) they weren't drinking on the job, but a 0.05% BAC measured after their arrest means their BAC would have been higher when they started breaking into the building earlier in the night.
