Zero Tollarence means no matter how stoopid you are all you need to do is follow the rules.
No, zero tolerance , as a general policy, means, those in charge are largely too stupid or too lazy to actually spend the time to understand a situation and make a reasonable judgement.
Its a cop out for laziness and cowardly behavior generally.
I don’t have to worry about making a tough judgement call, just follow a blanket edict without thought.
