In Ontario I was charged with possession of marijuana
I was searched In my school by my vice principal and she found weed in my bag.
She then took the marijuana and I showed some police, After a police officer walked in and told me it's under 3 grams so you won't be going to jail and that's it. After my vice principal called my dad to come pick me up from school, I asked her how much was there she said only a couple buds she didn't even weigh it , She informed the police but they didn't talk anything about me having possession of marijuana. She sent me home with my dad telling me that a police officer will be calling my house later. Later the police called and told me that I am being charged and being giving a court summons, the officer didn't tell me what I was being charged for and why I am being giving a court summons. Is there anything that Police Wrong here that can help me out in court please?
