Trespassing?

So about a week ago, I was walking towards my bus, about to go home. But as I prepared to board the bus, a stout man in a gray suit approached me and asked me if I wanted a Bible. I said sure, why not. At that moment, I was in such a hurry to get on the bus and get a seat that I didn't think to question the man about his intentions, or why he was handing out Bibles on school grounds (some say the place where buses park is public property; even if it was public property, it is so close to the school and kids, just because of its proximity and because it is where buses pick up school kids, that it directly affects kids and the school). Are people allowed to solicit (anything) so close to public schools (perhaps on school grounds)? Not that I have it in for this one guy. I think soliciting religion is the same as soliciting anything else. And one can even make the argument that solicitation of religion is a more serious matter because the product can have long term consequences or affects on "customers."

I wonder if this guy, handing out New Testaments to any kid who would listen to him, asked permission before he started handing them out. But what I really want to know is if this solicitation is a legal act. If this man had been selling cigarettes or some other dangerous substances, even though some seniors were 18 at that point, would we have mounted a full investigation into why he was selling cigarettes so close to a school? Would we have tried to move him far away from the school? I think so. I don't see the difference between advertising cigarettes and advertising religion. Isn't this person trying to force (although gently) his Christian religion upon schoolkids, the people most likely to be influenced by anything in this world, especially religion? Although we do have a Religions class in school, it is: one, an optional class; second, it is a class in which people interested about different religions study religions (as opposed to a class which either focuses on one religion or tries to convince students to believe a certain religion). In my personal opinion, I think this man was taking advantage of schoolchildren (whether consciously or unconsciously), finding a way to spread his faith easily among people who might be more open to solicitation than adults. I don't think this is a terrible offense. I simply think that the school should be more public about its policies for solicitation on and near school grounds. I think that if this man were to come to the school again, he would most likely face some harsh opponents and biting criticism.
