School solution: free lunch for cops
As with all the school weapon controversy, it is never simple. This is my first suggestion. I was an usher at a Chicago movie house. We allowed policemen into the theater free at any time, with or without being in uniform, some even with their family. They were armed.
Second: Offer free lunch to any policeman at the schools that have lunch or snack rooms or if they just wish to come in and use the washroom, uniforms or detectives.
Now to convince the school officials that it's better to have someone there with a gun before the killings start. Our Chicago neighborhood saloons/eateries welcomed cops to stop in and have a free sandwich or use the washroom or just to say hi. Security guards at no cost.
With some modification, it can be a win-win situation.
