Too bad, at least 2 good photos of the thieves and a pic of what one of them is riding...should be helpful in finding them...it should be har to sell the bike because of its rarity, etc.
If the shop has videos running during the day and has not erased them they might find the thieves casing the place earlier...certainly, they visited the shop beforehand and may be living in the area since they rode in for the heist.
As far as shoot on sight goes let's get real, comments like this in my mind make absolutely no sense.
