Enforcement in Maryvale features strict adherence to body-worn camera policies by the Phoenix Police, which can be pivotal in DUI defense.

Defense focuses on examining breathalyzer calibration records and body-worn camera footage from Maryvale PD and Arizona DPS officers patrolling the I-10 corridor near 59th Avenue.
