That Rotor Riot bridge dive - where do you stand?

(Edit) a lot of people have said stuff like "but they are professionals" or "are very skilled" but sometimes shirt happens to even the best pilots, including members of RR: (end edit)
They broke Transport Canada regulations by diving a bridge with cars and trucks on it -- but was this as bad as some folk are making out? Where do you stand on that video... was it just "great fun" or was it an unreasonable risk and unfair on the Canadian model flying community whose rights and privileges would have been at further risk if something had gone wrong?
And what do you think Rotor Riot could do to make their videos more entertaining without jeopardizing the rights and privileges of others?
Don't just think about it -- have your say in the comments below...
