Yes, they are taught to deescalate the situation when possible. IIRC, as soon as they pulled up the kids reached for the gun, which we now know is a toy, but the officer didn't have the luxury. He also didn't know the kids age. He also didn't know his gang affiliation or church membership. In a split second he had to consider he may die or shoot this young man. It is tragic. The cop isn't to blame. It would be helpful if the cops could meet more people so he would know his church membership and gang affiliation and who his momma is and the rest. That's not reality right now, though.
