Two sides to every story, and as the 2nd vid shows a whole group of riders were being jackasses on public roads and they all deserved to be busted. The guy who got caught most likely was doing it too, so don't feel so bad for him.
I guess you dont really notice the difference between stunt riders and regular riders bikes.....The guys doing the stunts have stunt bikes, most of them with no fairings...All of them have crash cages, 12 bars, flipped handle bars or dirt bars, etc etc.....The guy that was pulled over is a regular street rider, riding a minty clean street bike...On these big stunt rides generally %50 or less of the people attending are actually doing stunts, the rest are just along for the ride...
The only thing he may be guilty of is being along for the ride as a spectator IMO
