Yes it is, would people be this outraged at the cop if the kid had a gun and was intent on shooting up the playground? I wouldn't blame the kid or the cop for anything, I would blame the parents for letting their obviously autistic kid go out alone without supervision.
my biggest issue is about how it ended. the whole thing was fucked up, but he could have at least apologized when he found out the truth. he didn't. and he didn't even let the kid go for minutes still. the very moment he learned about the autism he should have let the kid go and said "I am sooooo sorry, kid."
Why would he be sorry? He was doing the job he was trained to do. That is why the parents should have been there, they could have told the officer that the kid has autism and none of this would have happened in the first place.
cop training is subpar in this day and age. the entire way cops are trained needs to be overhauled
