That one dude provides at least half of that town's GDP with the number of people gangstalking him! Wooooow!

That's why it's good to have family and friends around. They can't hide from all of us.

Also, getting out of the car and approaching them directly like a lion is always a good move imho. If they don't flee like the little cowards that they are, then you'll have a great opportunity to interrogate them while filming everything of course.
