Sad as it is to say, the system was not at fault - it was the pilot and crew flying in a reckless manner.
How can a system ever totally prevent that... in the same way as someone can pass their driving test and then go and drive like a maniac, you cannot legislate for poor judgement and reckless behaviour in the cockpit or in any other walk of life for that matter.
That said, may they all rest in peace as we were all young once, and I count myself fortunate that when I stepped outside the rules, I was lucky. There but the grace of god and all that.
