I've always found it amazing that some proof of checking passports etc at check-in isn't in force, considering the huge fines handed out.
However, I also think that perhaps the HS should be looking at better technology than a photocopier - a scanner would be cheap (so every c/in could have one - imagine the chaos if a central photocopier had to be used!), allow the agent to carry on checking in the pax while the passport was being scanned, and have an electronic copy that could easily (a) be kept secure from those who don't need access and (b) allow for easy deletion after a period of time.
My 2p worth, anyway.
