You are correct.
And most do not realize that the stand your ground laws do not change the laws. All it really does is give you a level of protection in court if you have followed the law.
Reaching in the window is the same as reaching in your window at home or in your front door at home and is plainly an attempt to do you harm.
I forgot to mention that different prosecutors read the same laws and get a different interpretation. It pays to be familiar with how your local cops and prosecutors interpret the law.
Obviously Chicago and Cook county will not read the law and get the same conclusion a prosecutor in FL or Texas.
