There is next to zero chance that anyone especially a trainer in the position that Gorder is in would knowingly or intentionally give their horse meth.

The idea that a street drug, especially Meth in the state of KY (meth capital of the US) , found at the picogram level wouldn't be the result of contamination is the hard to believe part.

It is close to impossible to police your horses 24 hours a day, 7 days a week. It is extremely hard to eliminate all human contact from your horses.
At the picogram level the horse could be contaminated by almost any contact. A maintenance worker from the track pees in the receiving barn stall after fixing a broken light bulb or cleaning the stall. A feed company employee. A test barn employee. Someone at the lab. Maybe the assistant trainer cashed his check before the race ad didnt wash his hands before putting on the tongue tie?

All sound a bit far fetched but a whole lot less far fetched than Gorder intentionally giving a first time in a year starter meth.
I'm amazed that people actually think that any viable trainer would try that.

The fact is that being a trainer nowdays is a nightmare. The rules are never actually spelled out for us, we virtually have no rights regardless of whether we are actually at fault, if we win too much we are suspicious, if we dont win enough we are clueless...

Often we arent getting paid for our services yet because a live animal is the the middle of this we have to keep on taking care of it to the best of our abilities or we are the bad guys. When a terrible incident like this happens despite it likely being completely out of our control, the internet judge and juries convict us instantly and we are blamed for the demise of racing and the euros disdain for our racing (they dont seem to like the NFL too much and they dont seem to worried).

Say you loan your car to your 17 year old kid to go to the mall. He picks up some of his friends and maybe one of those friends is a little shady and has a little bag of meth that he hides in the glove compartment when no one is looking. Now you get in the car and get pulled over for speeding and when you open the glove compartment out drop the little bag of meth that you had no idea was there. Cops arrest you for possession. Are you really a criminal?
