You get internal affairs involve.
When a cop arrests me , it usually happens that I ask him what his rights are .
sure why not u I'm a cop??
No. That is called a vigilante and could get you in trouble or shot by either side. Go become a cop if you want to stop drugs, but you can't do this on your own. You are not a superhero.
Yes, you can be.
They can get you on suspicion alone. If a cop has reason to believe then they have the right.
presumably, because if he/she were to confiscate the drugs one day, then get evidence that you were using/selling more of the same or different drugs.
Nothing. It goes on your permanent record, but nothing happens at all.
Not if you have been convicted in a court of law for it. Otherwise, yes.
If you're not using drugs, the investigation will find that out. Why are you worried?
there's a guy in tights on drugs flying around without the drugs
They are destroyed.
you die
