About five hours after the end of the first round of protests at the Society of Toxicology convention, protesters returned to target their 50th anniversary gala, sponsored by James River Laboratories, a contract vivisector just like HLS.

While a Beatles cover band played inside, piercing siren sounds and loud chants from bullhorns outside resonated and surely penetrated. The odds are near-zero that it was anywhere near being in key or tune with that Beatles cover band!

As attendees began leaving, they had to run a gauntlet of protesters, in some cases calling them the butchers they are to their faces.
