Family Dollar complaint: Harassment and refuting to let my daughter leave

Me and my family goes to this family dollar all the time. On new years day my daughter calls me all scared saying that a lady would not let her leave the store and said she was stealing the previous day. So I ran to the store to see what the heck was going on. When I got there the lady refused to speak to me I asked her why did she think my daughter stole something she refused to answer so I asked if she had called the police? She refused to answer so I told her I’m going to call th3 police myself that’s when she stated to me that one of her Co workers said they saw mu child stealing the previous day. So I told her to call the lady on the phone and I wanted to see the cameras showing my daughter stealing at this point the other Co workers stepped in and told me to come back the next day because only a manager can show me the tapes. So at that point I took my child and left. 2 minutes later her father called and told me to go back that he was meeting me there. So we went back and he called the police . At this point the lady changed her story and then said they manager said that my daughter stole something. So her Co worker called the manager and he said he did not know what she was talking about at this point I’m recording and have proof about all her lies. So one of Co workers and herself go to the back to review the cameras without the supervisor so finally the police show up like 10 minutes later so we approached the police explain what’s going on and where they are at so the police start to knock on the door where they are reviewing these cameras and they refuse to open the door. The police knocked once more and then pushed the door in. Again at this point I’m still recording. So I hear them ask them what’s going on and to see the cameras so the door is open and I can now see some what in this camera room. So anyway they say to the officer they cannot show her the camera because they supervisor is not there. So the the police tell them but you looking it over right now. At this point the police tells them we will review this camera so they look at the camera and then I hear the lady who said my daughter was stealing go.. look see she dropped something right there… so at this point the police officer tell this lady you cannot acuse people of stealing or hold anyone in the store if you do not have proof. So they come out and apologize and the same lady looks at us and smiles!! That was on new years! She never got in trouble and still currently works there!! I’m definitely contacting a lawyer about this. She held my under age child in the store for no reason. My daughter is scared out her mind now to go into stores by herself. She needs to be fired immediately! And I do not have any pictures but I have video footage of this hole incident and it won’t let me add it file to large
