I'm sorry, I don't understand what you mean, but I think we agree on sharing the common tax pot, no matter in whose account it is resting at the moment. All the schools have students that cross the streets. The taxpayers pay in to a tax authority that sends a portion of what they pay to various entities, like all the schools, etc. So your tax money - part of it - is in the accounts at D96, RB, etc. (Not sure about St. Mary's.) I think most people would favor those schools that have a surplus using the money for the intended purposes - education and safety of the kids. So I think the schools that have extra should chip in.
RB doesn't have it. But kids from Hollywood area go to Hauser and cross streets there. So the guards work for both districts there.
And complaining, arguing, etc. is the lifeblood of our system. We have primary fights that are very rough, but then people usually come together and work for the party candidate chose by the voters. When another party wins the losers are often disgruntled. Sometimes they refuse to cooperate as we have seen nationally. But life goes on. You probably like some things they do, and others not so much, and question many things. That's OK - but it's not the same as saying "I bet they have secret meetings and break the law" or some such. Everyone can say what they like, but that doesn't make it fact.
