A new investigation jointly conducted by ProPublica and FRONTLINE examines the excessive use of force by federal immigration agents against protesters and nearby citizens during the Trump administration. In an incident in Minneapolis, when a protester threw a snowball, federal agents responded with tear gas and pepper balls, as shown in footage and testimonies. The investigation states that federal forces used disproportionate and rule-violating methods while suppressing protests. Former law enforcement officials criticize these interventions, while some legal cases have collapsed due to video and witness statements. The events are considered part of the Trump administration's harsh interventions against protesters within the scope of immigration operations. The investigation thoroughly reveals allegations of excessive force used by federal agents targeting protesters and nearby citizens.
