Yeah the guinea pig was an odd fact - was it found in a cage? Also . . . "Police officers and BART employees were not allowed to ask for details of the disability of the person as well as the role of the dog they are with". More important not to have people say they have a medical issue, then safety. OK, then. I'm sure I'm not the only one who has thought about the mechanics about how she ended up 'on the tracks', and the only possible way is pretty gruesome. I'll spare a description. Some are critical of her tying her leash around her waist, and though I've not seen that, in most any circumstance that wouldn't be an issue, and this could only be a freak set of occurrences that resulted in her death. I this was a pet, not a service animal, it's time to end the niceties and begin the enforcement.
