To close a road or divert traffic, you need permission from the
authorities. So what they did was downright illegal.
On top of that, all those cars reversing in the middle of the
road could have caused an accident.
On top of THAT, emergency vehicles may well have been diverted
unnecessarily. Precious minutes could have been lost while
transporting emergency cases.
What they did was not harmless. I would applaud if the whole lot
of them were nabbed by the police and thrown into a Reformative
Training Center or something.
And for once, I actually support STOMP on this..... if they're
dumb enough to expose what they did on their own blog, then they're
just begging to be arrested.
