I once got pulled over for what a cop thought were overly tinted windows (they weren't) he then asked if I had drugs I told him i didnt and I had never even done drugs or even drank in my life. He continued to try to figure out if I had drugs and I said didnt I just tell you I dont. Then he said yeah that's what the guy said last week then we found some.

He needed a lot more to go on
