"Where there is a will there's a way" Everyone me included assumed the ETS system was safe and the manufactures and racing unions have covered all security risks before they approved them to be used, this risk should have been highlighted and controls put in place to stop it happening, something all unions will need to look at,. But surely the time his birds were marked on his sheet would not correspond to the time the marking station was open and suley he wasn't holding his own paperwork during the race? maybe a register of all members ETS times of marking should be used and verified at check and maybe the person marking shoud sign the sheets, this would stop this happening.
