Manly Protection

Here is the B3ta Question Of The Week:

Have you ever done anything that made strangers think you were a pervert?

Here is my submission, from college days:

One evening, my neighbor started screaming. A Peeping Tom was observing her from the bushes in the alley outside her bedroom window. In a panic, she came over to my apartment for manly protection. I locked her in, she called the police, and I went out into the alley to locate and confront the pervert.

So, who was the only one in the alley when the police helicopter and the canine units arrived?
