The video evidence

[McDuck]

we want solid concrete barriers...

Arnt they the barriers that we want? The Wire barriers are the ones we want to go. Showing people that will make them turn against those ones.

It's becoming clear that we don't want either in their present form. The armco barriers would only be preferable because they seem easier to modify (a low rail to cover the gaps).

That video was about a quarter as graphic as what happened on the 20th, Oct, 07.

The exposed legs and top of the post of all W section barriers also damage human body in major ways.

Just bumpted this as I think we need to remember what the video on this link showed, it may not be a WRB but the effect to riders is the same.
