I break the law to share the fun of FPV mini quadcopters

Showing reckless disregard for the law, I flew my mini quadcopter down at the local park the other evening and its bright LEDs in the late evening twilight soon attracted plenty of kids.
With those children running around, it wasn't prudent to continue flying so I landed and showed them the wonders of FPV glasses and video cameras on miniquads.
They were delighted and it was great to share at least a little bit of the fun with others.
Fortunately there were no 747s or Cessna's taking of or landing under the trees at that park or there could have been untold loss of life -- due to my breaching CAA101 by flying within 4Km of the local airfield and so close to civil sunset.
What's more, now that I've put this video on YouTube with ads, that flight is probably "commercial use" of an RC model and therefore violates CAA's "policies" with respect to such things as well.
Oh the humanity! Oh the carnage! Oh the risk to life and property!
Will the fun police arrest me? Will they arrest those kids, who were obviously also having fun?
