(Phoenix, AZ) -- Assaults against Phoenix police officers are up 45-percent this year. There are 419 cases that involved officers being punched, charged, spit on or shot at by suspects compared to 288 in all of last year. In addition, Phoenix police officers have drawn and fired their weapons more in 2018 than any previous year, with 33 officer-involved shootings to date. Chief Jeri Williams says she can't account for the reasons why aggression against police have increased but says she'll create opportunities for additional training for her officers.
