You have to move quickly because one cop fixes the lights and makes things a bit harder - you can take him out too actually if you go left from where you start and time things perfectly. Also don't underestimate the use of thrown items to distract people it's almost a must on hard.
I had it on the second hardest - it wasn't the uber difficulty because I think that actually shuts off instinct, but it was the one before that.
