Does a Chicago Public Schools Security Guard have the right to photograph me and my child without our permission?

This is in regard to an ongoing dispute between me and the security guard at Solomon Elem about where I can drop off my son (who is disabled, but not in a wheelchair, so the security guard does not think that his disability exists.) The problem is the rules change every month and they have no designated parent drop off area. They think the buses “have” to be able to drive where ever they want, even AFTER they have unloaded. But there are only a few buses. It is absurd. It has escalated to the point now that the security guard goes out into the street and hits parents’ vehicles and screams at us that we are creating “obstructions” that only exist in his mind. He scares us and our kids. He says we are “breaking the law,” but we are not considered to be PARKING if we don’t leave the vehicle. That is called STANDING. We want to be able to stop momentarily so we can see our kids walk into the building.

Then we move along. If you could see this you would not believe it. The neighborhood is completely quiet and peaceful. Without this insane person screaming in the middle of the street and hitting peoples’ cars, everything would be fine. There are numerous solutions that we have suggested to this problem–such as have the buses remain on one side of the building and the parents drop off on the other side– but nothing ever changes.

This has been going on almost 4 years. The principal comes out and says what we are doing is fine with her but the next day we have to deal with the crazy security guard going ballistic on us. I have become the special target of his nastiness because I am outspoken on behalf of my son because he is disabled and needs to be (a) dropped off close to the building and (b) supervised because he may wander off. So, the security guard has taken photographs of me and my child, to “prove that I am breaking the law.” But as I said I have not left the vehicle and the sign says “no parking.” It doesn’t say “no standing.”

Now, the latest is he called the 17th district police to try and get them to arrest me. I don’t think they can arrest someone on a parking charge, can they? (The police didn’t arrest me, and they also realized that I was standing, not parking, but they did not realize the entire history of the insanity. So they did nothing and left.) We complained yet again to the principal and the CPS admin and since nothing happened, this emboldened the security guard, and he has reiterated his “constitutional right” to photograph me and my son any time he wants to.

I don’t think he has this right because he is a CPS employee. Is this correct?
