The Maricopa County Transportation Excise Tax, often referred to as the “1/2 cent sales tax” is levied upon business activities in Maricopa County, including retail sales, contracting, utilities, rental of real and personal property, restaurant and bar receipts, and other activities. Transportation excise tax revenues are deposited in the Maricopa County Regional Area Road Fund (RARF) which is administered by the Arizona Department of Transportation. These revenues were the principal source of funding for the Regional Freeway System in Maricopa County and were dedicated by statute to the purchase of right-of-way, design and construction of new freeways, widening of existing freeways and highways, improvements to the arterial street system, regional bus service and high capacity transit services such as light rail.

Many Arizona street-level police officers and sheriff’s deputies report that they are skeptical of the ability of Arizona’s “pro-arrest” policy to reduce domestic violence, frustrated by a perceived lack of follow-up from prosecutors, and often at odds with victims whose predicaments they may not fully understand.

Domestic violence is a major social problem throughout Arizona, and a major daily challenge for law enforcement officers. Every day in Arizona, domestic violence injures victims, damages property, destroys families, breeds further crime and anti-social behavior, and perpetuates itself in younger generations. Like most states, Arizona has "criminalized" domestic violence (DV) by adopting laws and policies that bolster law enforcement officers’ arrest powers and require them to arrest suspects under certain circumstances.
