What are you talking about. How can you tell from that video he was gaining pleasure from that. It sounded to me like the kids were laughing a little more than the officer was.
Also, as previously mentioned, people don't know enough about animal behavior to make comments like "he was over reacting to this squirrel" This is not normal behavior for most wild animals, let alone squirrels. If it is coming at you like that there is something wrong with it.
What would have been a better solution. Should he have maybe kicked it away, (I am sure that would have went over like a fart in church). Or maybe he should have let the kids fend for themselves, have one or more of them get bit and have to go through painful rabies treatments.
He used a safe, non lethal process to get the animal to move away.
Again, never see the good in cops, only the bad.
By the way, they probably didn't call the police to come in to take care of this. In case you have been living under a rock somewhere, we live in a messed up world and we now have to have police permanently stationed at even our middle schools and some grade schools to protect the student body. (just not from rabid squirrels apparently)
