Video from Kenny Laynez-Ambrosio, 18, puts fresh scrutiny on the harsh tactics used to reach the Trump administration’s ambitious enforcement targets

On the morning of 2 May, teenager Kenny Laynez-Ambrosio was driving to his landscaping job in North Palm Beach with his mother and two male friends when they were pulled over by the Florida highway patrol.

In one swift moment, a traffic stop turned into a violent arrest.

A highway patrol officer asked everyone in the van to identify themselves, then called for backup. Officers with US border patrol arrived on the scene.

Video footage of the incident captured by Laynez-Ambrosio, an 18-year-old US citizen, appears to show a group of officers in tactical gear working together to violently detain the three men*, two of whom are undocumented. They appear to use a stun gun on one man, put another in a chokehold and can be heard telling Laynez-Ambrosio: “You’ve got no rights here. You’re a migo, brother.” Afterward, agents can be heard bragging and making light of the arrests, calling the stun gun use “funny” and quipping: “You can smell that … $30,000 bonus.”

The footage has put fresh scrutiny on the harsh tactics used by US law enforcement officials as the Trump administration sets ambitious enforcement targets to detain thousands of immigrants every day.

“The federal government has imposed quotas for the arrest of immigrants,” said Jack Scarola, an attorney who is advocating on behalf of Laynez-Ambrosio and working with the non-profit Guatemalan-Maya Center, which provided the footage to the Guardian. “Any time law enforcement is compelled to work towards a quota, it poses a significant risk to other rights.”
