Theft under 5000 first offense/minor
So first off I live in Quebec,Canada.2 days ago two friends and I were arrested for theft under 5000. It's a first offense for all of us. When they brought us to the police station we all stayed silent. Now my friend wants to press charges on the security guard from the store because he used a lot of force on her when it wasn't necessary and now she has 3 broken fingers. Where the security guard beat her up there were multiple cameras so should she press charges against him or will it make it worst for our case? Honestly I just want the charges to be dropped. I'm also scared because I know it takes a long time to go to court and I might be 18 by the time of the court date,what happens then? I spoke to lawyer on the phone at the police office and she said the prosecuter most likely won't even bring it to court,do you think that's true? What do I do in general? Oh by the way nothing was found in my bag.
