Residue is residue. It must be usable amount to be arrested for the drug possession charge to stick. And, possession of a marihuana pipe is a class C offense in the state of Texas, but it is an offense you can be, and in my part of Texas usually are, arrested for.
And, as far as it being pretty common for people to have a marihuana pipe, the fact that others do it doesn't have any effect on the legality of it. Whether or not it should be against the law is a political discussion, not a legal one.
The point of my post was pretty simple. Irvin did, by his own admission, break the law. He was arrested and charged, as he should have expected to be if he got caught. Whether it was someone else's pipe or not doesn't matter.
Whether anybody here believes his story or not is not relevant to his legal situation. The relevance in this situation is how this will impact his nomination for the hall of fame. I believe that Bob Hayes is not in the hall of fame primarily because of his drug problems after he retired. I think Irvin is attempting to deflect the blame in an attempt to avoid the same treatment.
I don't believe his story, but I also don't believe it should have any effect on his hall of fame voting.
