What if you are blind and falsely accused of shoplifting by an employee and bared from the store?

I was waiting for some fresh hot chicken to be displayed for lunch. I was told by a customer he is waiting also. I placed my bag on top of an ice cream box and open my bag to retrived my music device to listen to music until the chicken came out. As I stood leaning on the ice cream box listerning to my music a person approched me and asked me this, sir, did you put some ice cream into your bag? I replied, Ice cream in my bag, he( the employee )said yes, ice cream, do you know you could go to jail for this, just step over here and take it out and I wont call the police, if I call the police they will lock you up. I said, you are going to call the police, I don't have no ice cream in my bag.. I asked him why did you ask me something like this, he (the employee) stated that some one that doesn't work there told him they saw me put some ice cream into my bag and that by he (the employee) work here and they don't I came to ask you this. I told him again I don't have any ice cream in my bag.Remind you that I am blind and standing there waiting for the chicken to come out. I thought you came over here to assist or to see if I needed any help. I kindly asked him his name and he gave it to me. About a minuet later a plains clothes police officer came and identified himself and stated the manager doesn't want me in her store and the next time im in here i'll be arrested for trespassing. I stated to the officer that an employee accused me of shoplifting some ice cream into my bag. The officer stated that he didn't know that an employee had accused me of shoplifting and began to walk away, at that time I stated to the officer that being he is a commission sworn officer you and the manager or somebody is going to look into this bag, because I don't have any ice cream. The officer took a glance and the manager began to get loud. I was told to leave and was not to come back. I did leave without any confrontation with any one.. I am blind and I know I didn't do anything criminating in the store. What would you do? JAE.
