This is my take being in the area. Many PD's are becoming more anti as liberals are gaining power in the large metro areas.(Tucson & Phoenix) Remember Police chiefs are not elected. They are appointed by city Mayors. Combine this with tens of millions of dollars being poured into Arizona by the likes of Bloomberg and one can see a direct influence on those in government. The video on CBS 5 does not show the shots being fired, however they were kind enough to include a interview with a former prosecutor, in which he stated he would have reacted the same way and is doubtful the Maricopa Co. Prosecutor will take action on the charges brought by the Glendale PD.
On a side note - while many people carry in AZ less than .5% do so openly in the metro areas. This means that violent offenders are likely to mistake potential victims as being helpless and the chance of a gun battle are raised in my opinion. Concealed carry is an Offensive tactic, which for a civilian is a no no, only police have that option. While OC is a defensive tactic with a deterrent value. I wonder if this chic would have pulled her fake pistol if dozens of honest citizens would have been near all wearing sidearms?
Doubt it? I'm glad no one got hurt.
