You are all missing the point. Whether eating meat is right or wrong has no bearing at all. These pigs are someones property, and the government, specifically the CFIA, has very specific guidelines as to how this property needs to be handled before it is processed for general consumption among the public. She interfered with this process, trespassed on someone else's property by putting her hand through the truck, and potential disrupted the processing schedule, thereby costing the truck driver, the pig owner, and the procressing plant money and time. She should have been punished. 
The next point I need to make, is just absolutely how bonkers animal rights activists have become. Can we please focus just a little attention on actual human suffering and rights before caring about some dumb pig on a truck. Drives me absolutely crazy. Next time you think a pig is thirsty, bring that water to the hundreds of millions of children that are dying of thirst around the world...for shame.
