2 weeks ago we found a bag of what we tthought was cocaine and a bag that we know was weed. He is a cop so tells us its confiscated drugs and he called his supervisor in front of us to tell him the mix up. He told the supervisor and my dad claimed he was coming to get it and bring it down the station. I believed him but my sis and mom didn’t. They claim he faked the phone call. today i saw my dad smoking something and he threw it on the ground and stomped it to the ground outside. he thinks i didn’t see it and i played it off good. my father doesn’t smoke cigarettes. i told my sister about it and she told me she found more drugs with my mom in his jacket and she found cigarette papers.

how should i confront my dad about this, i dont want him mad at me.
