At the trunk or treat at the karate place, they had some police officers there to entertain the crowds a little with some cool stuff they do. I got to see the K-9 German Shepard dog. I will say, a criminal has to be dumb as a sack of rocks to willingly challenge a dog like that.
They also brought out the SWAT vehicle. Built like a tank. I figured our county had at least one of these things, I don't know if they ever had to use it for real. As anyone should know, if SWAT is present on a real mission, things are BAD in your neighborhood.
