100% agree.
Drunk men falling in rivers whilst walking home is an age old problem. It got so bad in Bristol people were actually thinking there was a 'serial pusher' on the loose as it was happening so often;

Going back to AK, you have to remember he had never been to Lewes before, and was very drunk. Whatever reason he left- to find a shop, train station, bus stop, just for a walk because he was in a mood- all he had to do was turn left and walk five minutes from his last sighting and he would be by the river. I think personally he was lost and disoriented trying to get wherever he was going and has had an accident, the exact circumstances of which are going to be tricky to ascertain unless more CCTV or a witness turns up.
Of course being pushed is not impossible. But on the balance of what is likely - he was seen on CCTV alone and not followed, I assume police have accounted for the rest of the group's whereabouts, is AK really going to have had an arch nemesis lurking in a town he's never been to before? Of course could be random but seems very unlikely to me.
My partner had an incident once where he almost ended up in a canal. Men just drink themselves silly when in big groups and take risks. I think there needs to be a national campaign to encourage men to not walk home alone, perhaps more late night police patrols near waterways, CCTV etc. In this day and age something must be done to stop these awful tragedies occuring. Personal responsibility is of course a factor but we can do more as a society to raise awareness.
