It is fraud though: they have/had an "other" category, but they called it "overcrowding" and then used the confusion on what overcrowding means to get funds (I'll bet when you hear overcrowding you think too many people not any of the many random things that can go wrong). Maybe it really is overcrowding, but since the category is really other we don't know.
Overcrowding is NOT a misc category, it is a specific situation with a specific definition (the exact definition is something they use should be published so we can decide if we agree with it), with specific training on how to tell if this is really overcrowding as opposed to a failure to get a normal crowd through in time since the solution to the two problems is different.
Other/misc is an import category to have - every system of collecting data needs to have a none of the above because there is always something you didn't think of. What is normally missing is that when other is used there needs to be a text explanation of what happened, and then an investigation to see what should be done. You collect data for things like "medical emergency" because from the category alone everybody understands that the delay is beyond control. When something is misc that means you didn't expect it and need to redesign your procedures so it never happens again. Thus the misc category should be something all operators hate to use: they get sucked into meetings on how do we ensure that it doesn't happen again.
