When you consent, you give them an opportunity to do some foul shyt breh.
I remember when I was in a white town in Louisiana with my homeboy. He asked me to drop this random white girl from the gas station off. I did and as soon as she left the car, the police pulled me over. They asked where I was coming from and I told him that I dropped some girl off that asked for a ride at another gas station. He asked if I had drugs in the car and I said "not unless y'all put it in here". He asked how would they put it in there? I said "y'all prolly set me up. I just dropped off a white female and you pulled me over. Plus I'm a black man" He said he couldn't see what color I was and that I was in a high drug area. I told him "come on now,...I'm in a Cadillac and you said I'm in a drug area." He went back to the car and came back and said "You sure it's no drugs in here?" I told him again, unless she dropped it back there on purpose ain't nttn in here". He asked me does he need to get the k9. I told him "you gone be wasting ya time". He eventually let me go and my homeboy was talking bout I was gone get us killed talking to that white cop like that
