I called out the cops on my neighbor's son and his friend when they were lurking in my garden but all I saw were two young men standing at the top of my front garden at about 2am and then racing around to the back of my house. Of course I called the cops, and I remember my voice shaking when I did so. And of course I gave the best description I could, they appeared to be white, late teens, casual clothing, that kind of thing.
