The California Faculty Association, an “anti-racism, social justice union” that has 29,000 members, claimed on Instagram Saturday that “four masked agents” put CSU Channel Islands professor Jonathan Caravello into an unmarked vehicle “without identifying themselves” or giving a reason for the arrest.

“The arrest of Professor Caravello was an outrageous abuse of power and an attack on basic freedoms,” said Rocío Sáenz, Executive Vice President of SEIU. “His release is a step toward justice, but thousands of working people remain unjustly held.”
