I was stopped at the age of 13 for birdwatching of all crimes. I was walking at sunrise with a small backpack and pair of binoculars. Got stopped by two Sheriff's deputies who had nothing better to do than jack me up. They got pissed that I had a small Swiss army knife. After showing them my backpack just had snacks/water and a birder's guide, they still took an hour to let me go. I'm sure tons of runaway kids have birdwatching gear as cover to fool the authorities. ACAB.
