It used to be higher because of all the illegals! They'd murder someone, then get deported, then come back and do it again!
Illegals who commit murder are jailed in AZ, not deported*. Mexico has asked Arizona to deport criminals who were subject to the death penalty. Arizona declined to do so.
As for why AZ citizens wanted constitutional carry. Well I was an AZ resident for over 20 years until last month and I can tell you it had more to do with how silly it was that a simple permit suddenly allowed you to CC. Also, there was the whole shirt flap scenario. Is it concealed under the moving shirt flap or is it partially visible (as required by law to be considered OC and thus legal) as the person moves around? Additionally, there was the car transport issue. We didnt want to have to have our guns in the open.. stashed under an arm rest for instance was considered concealed carry. If some notebook or papers slid around on your seat and inadvertantly coverd your gun, that was an example of concealed carry.
In short, the laws differentiating between OC and CC were just plain silly. In AZ there's not enough liberal politicians currently in power to block common sense and clearly stated Constitutional rights.
To argue against anyone who opposes CC, one has to merely point out that in ALL instances(including AZ in spite of its huge influx of illegal aliens), the crime rate went DOWN after CC was instituted. There is no State example where the murder rate went up once CC was allowed.... not a single one.
* Of those in AZ jails who have committed murder, 13% are illegal aliens, yet illegal aliens only make up 7% of the State population.
