Today 2 undercover cops came to my house.I was outside they got out and said they needed to talk to me.I live in south carolina.They told me they had a tip I was growing pot in my home and wanted to know if they could look around.I told them I was not doing that and no they could not come inside.Told them to get a warrent that I was busy fixing my truck .They said ok but they would be back to check up on the tip.They let and drove up and down the road from sometime.My house is clean theres nothing fishy.What should I do?what should I be on the look out for?
