How to keep player from clipping through dead models?

[170646]

How do I keep Gordon (the player) from clipping through dead things, such as enemies I just killed, etc. On the 2nd or 3rd _trainstation map, when in the tennents, where the CP breaks down that door and starts beating some guy up (you cant go in there, are blocked by a cop), I clipped back there and when I enabled clipping again, I could move the body in there around just by walking into it. This really added to the realism of the game, how do I make this work all of the time?
cl_ragdollcollide 1, doesnt seem to work for me.

ragdoll_collide is just a function to make 2 ragdolls hit eachother. Not the player.
