This is overdue - Victoria Police announced it was rolling out a new squad to help combat crime on Melbourne's streets. Picture: Victoria Police! A specialist range of wheeled police known as the "Roller Squad" will patrol "car-free zones, malls and bicycle paths".

I had the privilege of sharing the stage with this hero, Bristol Officer Alec Iurato. Officer Iurato survived an ambush attack that started as a 911 hoax. Bristol Police Lt. Dustin DeMonte and Sgt. Alex Hamzy were killed & Iurato was able to, fire 1 shot killing the assailant.
