Despite knowing the fact that Evans was always breaking out of jail, the prison authorities still made many mistakes. The following were the mistakes committed by them: The validity of the German tutor not checked. Evans allowed to sit for an exam knowing he wasn’t academically inclined and not checking whether he had learnt any German at all. Letting Evans see the name of the invigilator on the form. Not taking more precautions in verifying the invigilator’s identity despite knowing Evans knew his name. Letting Evans wear the cap for good luck. Allowing McLeery to take the rubber tube inside. Not going into the cell despite seeing that Evans was just sitting there not writing at all.Not verifying the Governor’s phone call. Despite seeing that McLeery looked slimmer while going out, not checking him. Appointing Stephens, a new guard, to guard Evans. Allowing Stephens to move out of the cell when Evans protested. Letting Evans know that the cell was bugged.  Letting the Examination Board phone call go through without verifying its authenticity.  Letting Evans put on a blanket over his shoulders Believing Evans had left the correction paper behind by mistake and believing the information in it. Calling for the police, not the ambulance. Letting Evans escape a second time in a van without verifying the guards  Everyone just accepting Stephens’ belief that the man in the cell was McLeery as he was bleeding and did not check his wounds. Getting fooled by Evans pretending to be McLeery although everyone knew Evans was a good mimic.
