Apart from a little more control by the staff at the gate and a policy of prosecuting in 100% of these cases ( both criminal & civil) I can't see anything that needs to be done as any other measures are just infringing the rights of the vast majority of the law abiding passengers.
Sorry to say old chap, but you´re too late.
In current times, we forbid more because previous bans on the same subject have not produced the desired results.... that happens everywhere, like on the road where the limit was 100km/h and 4 drunk teens/twens kill themselves with massive overspeed, the authorities then put up a 70km/h sign, cause its a "accident hotspot". Won´t help the drunk drivers going too fast, but hey, never mind...
