Cyclist killed, let's block the streets...

Cyclist (51) killed in Dublin crash

(From Irishtimes.com)

"A cyclist (51) has died following a collision in Dublin City Centre this morning.
The man was fatally injured when he collided with an articulated truck at Wellington Quay at about 8.20am.
He was pronounced dead at St James' Hospital a short time later.
The road remains closed at the scene to facilitate forensic collision investigators carrying out an examination of the scene and diversions are in place."

Can we arrange a protest... each time I read of this I feel the need to take to the streets, to block traffic in protest. These streets are not safe for us!
(Although I don't know the full details of the accident).
