"there have been challenges"
Challenge #1: imagining that school children would play nice. Result ? FAIL.
Challenge #2: thinking that your code was resistant enough to keep children in the straight and narrow. Result ? FAIL.
Challenge #3: persuading people that not being able to use the core component of the tool (accessing educational content) is just a challenge. Result ? ABJECT FAIL.
Challenge #4: Persuading the police that you had no idea that your insufficiently tested platform was going to be such a clusterfuck. Result ? PENDING.
And, as for standing by your performance, I sure hope you will be made to. All the way to prison.
