Activists raid Wisconsin beagle lab

The chaotic scene unfolded on Saturday as about 1,000 protesters tried to breach the property's perimeter.

Law enforcement arrested the group's leader and several others during the confrontation, which marked the second raid attempt in as many months.

Activists claim the facility subjects the animals to barbaric cruelty, while the owners maintain they follow all federal research guidelines.

The incident has reignited a national debate over the ethics of animal testing in the pharmaceutical industry.
